How Creatnine Supplements Can Benefit Us
Creatine is generally known as an amino acid produced in the body and can be obtained from meat and other animal products. Creatine is also scientifically termed as creatine monohydrate. It is a crystalline and transparent chemical that the muscle tissue uses up in producing phosphocreatine. Phosphocreatine is an important ingredient needed to form the adenosine triphosphate. Adenosine triphosphate (ATP) serves as the source of energy for the contraction of muscles and other functions of the body.
Creatine is converted into the molecule known as phosphocreatine, which is important for the tissues including voluntary muscles and the nervous system. Energy in large amounts is needed in these specific parts of our body.
The potential of creatine to enhance the performance of athletes in situations where large amounts of energy are required has been emphasized in several studies. Bodybuilders seem to be the group who pays the greatest importance to creatine. Athletes who are participating in endurance activities are not recommended to take creatine since creatine caters more on muscle mass, and these athletes should focus more on muscle endurance. Nevertheless, muscle mass may also be caused by other factors such as water retention, aside from the increase in muscle tissue.
The advantages of creatine in neuromuscular disorders have been emphasized in two scientific studies. Flint Beal of Cornell University Medical Center conducted a study that received fundings from MDA. Beal's study emphasized that creatine was stronger and more effective compared to riluzole, a prescription drug, in prolonging the lifespan of mice suffering with amyotrophic lateral sclerosis (or Lou Geghrig's disease), considered to be a degenerative neural disease. Another study was made by Canadian researchers, Mark Tarnopolsky and Joan Martin from McMaster University Medical University in Ontario. This study highlighted that creatine can lead to minor increases in strength among individuals afflicted with neuromuscular disorders. The March 1999 issue of Nature Neuroscience published Beal's study while the study of Tarnopolsky and Martin sought publication in Neurology March 1999 issue.
No negative side effects have been reported yet by most of the athletes who have been taking creatine. However, several reports confirmed the link between using creatine and kidney damages. However, creatine supplementation has not been reported to be a potential cause of toxicity as of the moment. But, taking creatine may lead to difficulties or complications in dehydration.
Taking an initial dose of 20 grams per day for five or six days is prevalent among athletes. After that, they proceed to a maintenance dose of 2 to 5 grams per day for the succeeding days.
The long-term causes of supplementing creatine have not been studied yet. Diarrhea and muscle cramping are the most evident negative effects of supplementing creatine. Some reports also revealed that short-term small amounts or long-term big amounts of creatine supplements do not have any effect on the functions of liver and kidney among healthy young adults. Kidney function was not altered even after five years of creatine supplementation, as revealed in a study of individuals taking 5030 grams a day. However, some studies provided anecdotal reports of muscle cramping after creatine supplementation.

Discount Creatine
Creatine is a non-protein amino acid that is produced by the human body. It is produced by the liver, kidneys and pancreas from existing amino acids and from the food we take. Creatine helps in the production of adenosine triphosphate (ATP), which is a major source of energy for the body. The body produces 2-4g of Creatine daily. The main food sources of Creatine are fish and red meat.
Creatine is used as a dietary and food supplement, especially by sports people. The ability of Creatine to generate sudden bursts of energy when the body is exerted makes it an effective drug for people participating in sports like weightlifting, wrestling or sprinting. Creatine content in the body can be improved marginally by consuming more red meat and fish. But for some extra Creatine, most people depend on Creatine supplements available in the form of tablets, capsules or powder. Creatine supplements are approved by the FDA as a food supplement and are considered to be as safe as vitamin supplements though caution should be taken regarding the dosage. However, taking too much Creatine is also not very harmful as the body can absorb only a certain quantity and the rest is expelled from the body through the kidneys.
There are several Creatine supplement products in the market today. These are available in different forms and sizes meant for different kinds of people. Creatine supplements are available in different flavors and even in chewable forms. Discount Creatine supplements are also available at lower prices ranging from £4.99 for a 100g bottle, £14.99 for a 500g bottle and £21.99 for a 1KG bottle. There are many websites over the Internet that offer advice about discount Creatine. The products can also be ordered online. Wholesale dealers are another source of obtaining discount Creatine. Buying by bulk proves to be generally much cheaper.

Andre Agassi's Drugs Confession
In his autobiography "Open", Andre Agassi controversially confesses to taking the recreational drug crystal meth while competing on the ATP tour back in 1997, and perhaps even more shockingly, to asking / allowing a friend to take the rap when he failed a doping test around the same time. Now, if it had been bad-boy John McEnroe who had made the admission, perhaps no one would have been that surprised, but the fact that it was Andre Agassi, who was (and still is) regarded as one of tennis's greatest ambassadors makes it doubly unpalatable.
Andre went on after that episode to regain tennis's top spot and win numerous titles - one wonders what would have happened if he'd been banned for his drug-taking. Would his career have taken off in the same way? Obviously we'll never know. Andre has since expressed his regret over the incident, but the question is: why did he feel the need to make the disclosure in the first place? What does he hope to achieve?
Marat Safin, another former world number one and grand slam winner, recently had the following to say:
He feels guilty? So let him just give back his titles, money, his grand slams! If he is so fair play, he should go all the way. You know, ATP have a bank account, he can refund if he wants to.
Safin also goes on to speculate about Andre's motives for the disclosure, suggesting that it's all about selling his book. There may well be substance to that - I've certainly not heard a more convincing reason yet. At best though, one feels that it's an ill-advised move which is unlikely to enhance Agassi's reputation. Fortunately he has a lot of moral capital to draw on, built up by years of humanitarian and charitable work.

What Your Doctor is Prescribing Could Be Robbing Your Memory - Part II
In Part I of Memory and Aging, I explained to you how growing older can affect your memory. I also gave you some brain-healthy things you can do to keep that incredible shoulder-top computer retrieving all its data well into your advanced years.
Here in Part II, I would like to talk to you about prescription drugs, and the impact they can have on your brain function and your memory. Then we'll talk about some natural supplements and how they can help you retain more of your memory.
Each category of prescription drugs has a multitude of individual drugs that can be prescribed to you for common ailments like sinus problems, infections, insomnia, nausea, etc. The effects on your memory can range from temporary short-term memory lapses to broad, long-term memory wipe outs.
In the list below, I've included the types of prescription drugs that can damage your memory.
PRESCRIPTION DRUGS THAT CAN CAUSE MEMORY LOSS
Analgesics
Anesthetics
Antianxiety
Antidepressants
Antibiotics
Antihistamines
Antihypertensives
Anti-Seizure medications
Hormones/steroids
Nausea Drugs
Parkinson Disease Drugs
Sleep Aids
Ritalin
Statins
Mother Nature To The Rescue
With all the pharmaceutical drugs out there that threaten to damage your brain and your memory, the good news is that there are several vitamins and natural, herbal-derived products that have brain-health preserving and memory boosting properties!
The most significant group of vitamins that enhance brain health and memory are the B vitamins, especially B6, B9 (folic acid), B12, citicoline. B vitamins protect the nerve sheath covering brain cells. They pulverize homocysteine, a nerve cell toxin, and carry oxygen. A healthy diet filled with citrus fruits and dark green, leafy vegetables, and/or supplement, aids good brain function.
Next, antioxidants like Vitamin C, E, and beta carotene, give critical protection to brain tissue by dissolving free redicals that cause damaging oxidation. These nutrients can be found in citrus fruits, yams, and wheat germ/oil and are also a staple of good vitamin supplements.
Beneficial fatty oils, like Omega-3 fish oil, help protect the brain cells by neutralizing inflammation and cholesterol deposits. Fatty fish like salmon or fish oil supplements of 1,000 mg a day ensures optimal brain levels of this nutrient.
Below, I've listed several, herbal-derived supplements that are beneficial to your memory.
NATURAL SUPPLEMENTS THAT HELP IMPROVE MEMORY
Alpha GPC - supports attention, focus, recall, and other brain functions.
Adenosine Triphosphate (ATP)- supports concentration and focus.
CoQ10 - helps with overall body energy, supports concentration and memory.
DMAE - helps with alertness and concentration.
Gingko biloba - improves blood/oxygen flow to the brain.
Huperzine A - aids age related memory loss; boosts short-term memory.
L-Carnitine - an amino acid that aids brain energy.
L-Glutamine - works as a brain transmitter, aids concentration and alertness.
Lion's Mane Mushroom - enhances mental performance. Aids in nerve/brain cell growth.
Vinpocetine - improves blood flow to memory storage center of brain.
What You Can Do
As I've discussed here, you don't have to be resigned to memory loss. There are some excellent natural sources of supplements, as well as vitamins, available that can help keep your brain and memory functioning optimally.
If you take any of the classes of prescription drugs noted here and seem to be experiencing memory problems, please contact your physician to discuss your concerns.

What is Insulin Resistance? And How Do Antioxidants and Exercise Help Lower Blood Sugar Levels?
Type 2 diabetics are told their condition results from insulin resistance, that insulin resistance is a forerunner to type 2 diabetes. But insulin resistance is usually given a circular definition such as "insulin resistance is resistance to insulin." So, what is insulin resistance really?
If you have a good idea why the body needs antioxidants, you can easily understand insulin resistance.
glucose is the most important fuel for the mitochondria, the "furnaces" inside every cell
the mitochondria are the principal energy source of the cell and converts nutrients into energy as well as doing many other specialized tasks
cells use glucose to make the energy storage molecule ATP. They can store energy from "burning" glucose with the help of oxygen, or they can make energy from glucose even without oxygen
The first process is known as aerobic respiration. The second process is known as anaerobic respiration... anaerobic respiration requires about 30 times as much glucose as aerobic respiration. That's why any kind of exercise that induces the feeling of a burn in your muscles, or that causes you to get out of breath, is so good for lowering your blood sugar levels.
About one in ten million oxygen molecules escapes the mitochondria and becomes a free radical. These toxic forms of oxygen can damage your cell's outer lining. They can cause mutations in your DNA and they can wreak havoc with the biochemical processes that keep your cells alive.
The more glucose your cell burns, the more oxygen molecules escape normal channels, and the more damage is done to your cell or cells. To protect themselves from a flood of glucose when blood sugar levels are high, cells become resistant to insulin. This protects them from free radical damage.
This is why antioxidants, such as vitamin C and alpha-lipoic acid, can actually lower your blood sugar levels slightly. Antioxidants make it possible for cells to stay healthy without becoming quite as resistant to insulin.
In most cases of type 2 diabetes, however, insulin resistance becomes a self-sustaining process. Cells resist insulin, so glucose stays in your bloodstream. The pancreas senses high blood sugar levels, so it releases more insulin. In turn, cells have to become even more resistant to insulin, blood sugar levels go even higher, and your pancreas produces even more insulin... until at some point the insulin-producing beta cells "burn out".
Reversing the process of insulin resistance is key to managing and even reversing your type 2 diabetes. Medication, diet, and nutritional supplements all help, especially a vegan raw foods diet to reverse type 2 diabetes.

Our Body Uses Chemicals and Electrical Impulses For Communication
Introduction:
The central nervous system uses electric currents to communicate with the rest of the body. Sodium and potassium are responsible for causing the flow of the electric currents throughout the central nervous system. The flow of the electric current is a one-way process, terminating at a pre-synaptic neuron. Another chemical comes into play, namely calcium, which, with sodium and potassium, cause the release of further chemicals called neurotransmitters, which aid in the communication process.
The central nervous system (CNS) is composed of the brain and spinal cord. Signals from the CNS go, via a one-way system, to the motor neurons, which in turn communicate with the somatic (voluntary) muscles and the autonomic (involuntary) muscles to produce movement.
Sensory neurons, send signals to the CNS, via a one-way system, which interprets the information and acts accordingly. For example if person stands on a sharp nail, the information is communicated to the CNS, the brain then informs the foot, to move away from the source of the pain, all done within milliseconds.
But how is this achieved? It is all a question of chemical and electrical processes.
The cell body of the neuron initially receives the signal, or stimulus. This signal is transmitted down the neuron's axon, starting as an electrical impulse at the axon hillock.
Without any stimulus the neuron remains in a resting state. Even during this resting state there is a constant flow of chemical ions between the inside and outside of the neuron, due to the ion concentration gradient, which produces a difference in electric charge between the outside and inside of the neuron, which is called the resting membrane potential. During this stage the inside of the neuron is negative in relation to the outside which is positive. The resting electrical potential is approximately -60 mV.
The main chemical ions involved during the process of communication are Sodium ions (Na+), the main extracellular cations and Potassium ions (K+), the main intracellular cations. Within the cell there is concentration of 140 mM (millimoles per litre) of K+ ions and 15 mM of Na+ ions. Outside the cell the concentration is 5 mM of K+ ions and 150 mM of Na+ ions. This gives rise to two concentration gradients, where ions of a high concentration will try to pass through the plasma membrane of the axon to a low concentration of the same chemical ion. For example, the high concentration of K+ ions in the cell will attempt to pass to the outside of the cell where the concentration is less. This occurs continually via K+ channels, which are constantly open, allowing a constant flow of K+ ions through the channels in the membrane to the outside of the cell. There are voltage-gated Na+ channels (VGC), which are closed during the resting potential, thus preventing the Na+ ions from entering the cell. There are also chemically-gated K+ channels (CGCs), which are also closed during the resting potential. A chemically controlled gate is also called a Ligand gate. The channels are classed as passive transport, as no energy is required to power them, they rely on the concentration gradient to move ions from one area to another. Apart from ion channels there are sodium-potassium (Na+- K+ ) pumps which actively expel Na+ ions from the cell and exchanges them for K+ ions from the outside of the cell/plasma membrane. The Na+- K+ pump simultaneously transports 3 Na+ out of the cell and 2 K+ into the cell. The pump is classed as active transport as it works against the concentration gradient and requires energy in the form of ATP to power it.
K+ channels are the most common open channels in the plasma membrane of resting neurons, therefore resting neurons are more permeable to K+ ions than any other ion.
If neurons receive input signals from one or more cells, the neuron will generate an electrical signal or action potential which will travel down the length of the axon, starting at the axon hillock. On receiving the electrical stimulus, the VGCs will open, allowing Na+ ions to flood into the axon, which changes the charge from negative to positive. The CGC's will also open, allowing the K+ ions to flood out. This depolarising current then moves down the axon, opening up more VGCs and CGCs as it goes. However, as the electrical current moves forward, there is no current where the impulse started and so the VGCs and CGCs close, preventing more influx of Na+ ions and expulsion of K+ ions. The Na+- K+ pump then starts to expel the Na+ ions from the cell and exchanges them for K+ ions from the outside of the cell, thus re-instating a resting potential. There is also a refractory period of 1-2 milli seconds, where the VGCs cannot reopen, thus preventing (backup) of the current. It acts as a valve so that the current can only move in one direction. The current moves along the axon like a lit fuse, opening and closing channels as it progresses.
Eventually the current reaches the synaptic knobs, which are bounded by the presynaptic membranes. The synaptic knobs come into close contact with the dendrites and cell body of the post synaptic neuron, but do not touch the surfaces, there is a gap called a synaptic cleft.
The presynaptic neuron has now to communicate with the post synaptic neuron.
As the action potential arrives at the axon terminal, VGC's in the synaptic knob membrane open allowing Na+ ions to flow in to the knob. This depolarisation causes VGC's of Ca2+ ions to open. Ca2+ ions flow into the knob and trigger a fusion of vesicles, containing neurotransmitters, with the cell membrane. The neurotransmitter/s are released across the synaptic cleft and bind to ligand-gated receptor channels on the post-synaptic neuron. The receptors are activated into opening the ligand-gated channels of Na+, K+ and Ca2+ causing these ions to flow in to the post synaptic cell and depolarise it. The depolarisation spreads in the post synaptic membrane, firing an action potential within it.
There are different types of neurotransmitters, which are all chemically based. They include acetylcholine, monoamines, purines, amino acids, peptides and gas (nitric oxide). Each neurotransmitter can work alone or in combination with each other, depending on the required effect. For example, if the above action potential arrived at a muscle, the released neurotransmitter would be acetylcholine. The action potential firing in the post synaptic neuron (muscle) would cause movement in that muscle.
Conclusion
In order for muscles to move, voluntarily or involuntarily, the brain must communicate with the muscle in order for it to move. The brain does this by sending a signal to the muscle. The signal is the result of chemical and electrical processes passing along neurons, which in turn pass that information on to other neurons, for example, muscle neurons.

Frequency Specific Microcurrent Offers New Hope For People With Chronic Pain and Fibromyalgia
Approximately 10 million Americans suffer from a condition known as fibromyalgia
syndrome. This condition is characterized by widespread muscle pain, extreme
fatigue and chronic non-restorative sleep disturbances for more than three months'
duration. Although pain and inflammation are among the symptoms, they are not
the cause of the disease. Therefore, treating the inflammation and pain of
fibromyalgia with anti-inflammatory drugs, pain medication or even natural
remedies is rarely effective.
There are four common traumas that can cause fibromyalgia. Most patients with
fibromyalgia have experienced one of the following events 4 to 12 months before
their symptoms appeared: (1) neck injuries or cervical spine trauma; (2) toxicity or
chemically induced trauma; (3) acute or prolonged severe emotional stress; and (4)
immune system trauma from unresolved viral or undiagnosed illness.
Although these traumatic events seem unrelated on the surface, each one can be
the precipitating cause of two systemic problems present in almost every
fibromylgia patient. The first effect is damage to the neuroendocrine system,
resulting in adrenal exhaustion and hormonal imbalance. The second effect is the
reduction of cellular energy in the mitochondria, which is the power-producing part
of the cell. Recovery from fibromyalgia requires that all causative factors and the
hormonal and cellular energy production problems be addressed and corrected.
Although this approach has been effective with all types of fibromyalgia, this article
will address the evaluation and treatment of fibromyalgia caused by cervical spine
trauma. Approximately 25 percent of patients with fibromyalgia report the onset of
pain following a cervical trauma. The most common injuries result from motor
vehicle accidents (whiplash), surgeries, trauma from falling down or injuries from
lifting or moving heavy objects.
The symptoms associated with cervical truma-induced fibromyalgia include: neck
pain; burning pain between the shoulder blades, shoulder, arm, hand, back, leg and
foot: headaches; fatigue; weakness; sleep disturbance; depression; and digestive
problems. Patients with this type of fibromyalgia complain of aching, burning,
sharp, shooting and/or stabbing pain.
A new treatment called frequency specific microcurrent (FSM) offers hope to patients
with fibromyalgia. A clinical trial of 160 patients with cervical trauma-induced
fibromyalgia treated from 1999 and 2003 was conducted using FSM. On a
subjective pain scale (1=no pain to 10=severe pain), these patients reported an
average pain reduction from 7.3 to 1.3 after their initial treatment with FSM.
The treatment involved the use of 200 to 600 microamperes of direct electrical
current to the spinal cord. Condition and tissue-specific frequencies are utilized to
effectively reduce the inflammation in the spinal cord and restore normal nerve
conduction. Most patients benefiting from this treatment were pain-free for the
first time in years. The initial pain relief lasted five to 48 hours and was the start of
recovery.
Follow-up FSM treatments were conducted twice a week and most patients required
daily use of a home FSM unit to control the pain. The average number of treatments
to remain pain-free was 10 treatments.
Recent studies have determined a biological mechanism for the result seen in
patients. FSM treatment affected the serum levels of several biochemical
constituents including IL-1, IL-6, TNF-a, Substance-P and LOX, which are
inflammation/pain-related biological chemicals. All were significantly reduced
when measured after the FSM treatment. There was also a dramatic increase in b-
endorphin, a naturally-occurring chemical which helps reduce pain, and a 500
percent increase in ATP, the body's fuel storage molecule used in cellular energy
production.
Dietary changes and nutritional supplements were combined with the FSM
treatments to address other contributing factors, such as the endocrine and cellular
energy weaknesses in all patients. Furthermore, depending on the individual needs
of the patient, the following imbalances were corrected before a lasting recovery
could be reached: neurotransmitter (serotonin and catecholamine) deficiencies,
digestive problems, liver, adrenal, and thyroid dysfunction, soft tissue and joint
problems, and unresolved mental/emotional issues.
Beyond alleviating the effects of fibromyalgia, FSM also has shown great promise in
the successful treatment of athletic injuries, chronic or acute joint pain/stiffness,
pain associated with gall stones and kidney stones, closed head injuries, shingles,
post herpetic neuralgia, infections, diabetic ulcers, wound healing, and other
conditions that are often unresponsive to conventional medical treatment.

How the DP Exercise Bike Stacks Up Against Better Known Brands
The name DP exercise bike might not be as recognizable as other brands like Schwinn, Nautilus and ProForm, but this brand has been around for quite some time and is one of the most respected names in the physical fitness business. Currently, DP is better known for selling exercise bike parts and exercise equipment supplies.
Most DP indoor bikes are old models and are quite difficult to get hold of except in online stores and secondhand retailers. One of the models of DP that became quite popular was the DP Fit for Life Airgometer upright bike. This model costs around $1,000 to $1,200 and carries the basic features of an upright indoor bike.
Another model from the DP fitness brand is the Vita Master MBP2. It features various program settings and tension controls. It also has a heart-rate monitor and features battery operated controls. Aside from the Vita Master and the Airgometer, DP also offers DP Air Advantage, DP AirCisor, DP Prime Fit 6100, DP Sit for Life Aircizer and DP Vitamaster MD193.
DP has been overshadowed by more recognizable brands like Schwinn and ProForm. Schwinn, for one, has multiple models out in the market, including the 230 recumbent bike, the 130 upright and the Airdyne exercise bike. Scwhinn's products can cost from $350 to over $1,000. One of the brand's more expensive model, the Evolution, sells at more than $1,000 and has been highly rated by product reviewers. It features an inertia drive system, adjustable resistance and direct drive gearing.
ProForm, another brand competing with DP in the indoor bike market, offers machines that cost $150 to $1,200. One of its low end models is the SR30. The features of this machine are very basic and the model is geared at entry level market. It features magnetic resistance, pulse sensors and an LCD console. Other ProForm models targeting the low end and middle markets are the SR80, GL 35 and GL 105.
The DP brand might not be at the top of the market, but its machines still serve the basic operating functions of exercise bikes. They offer users the ability to tone and strengthen leg and thigh muscles and provide an effective cardiovascular exercise routine. Limited availability aside, DP exercise machines, including the secondhand models being sold in online auction sites, might still be worth consumers' time and investment.
The DP exercise bike is not exactly hogging the physical fitness equipment limelight, but there are still those who like the brand. For these loyal customers, auction sites and online stores are their best options of finding one these products.

Stun Gun - Physiological Effects
Have ever watched the TV show Star Trek and heard of the Romulan disruptor stun weapon? Have you ever thought about what it disrupts? Does it disrupt all the molecules in the person on the receiving end of the ray gun? What about a real stun gun? What does a real stun gun disrupt?
In this article, I will attempt to explain to you what a stun gun does disrupt on the scientific level.
The basic premise of a stun gun is to disrupt the communication superhighway between the brain and the peripheral nerves.
In general, stun guns put out a high-voltage, low amperage charge. Simply put, the stun gun exhibits a lot of punches but lack of power behind those punches. It is kind of like a 3-year-old kid punching the heck out of his daddy's face but does not have enough force behind those punches to put his father in the hospital.
Upon depressing the stun gun's trigger, the electric charge passes into the perpetrator's body. Because it is high voltage (lots of punches), the electric charge will pass through thick clothing, fat under the skin, and subcutaneous soft tissue, particularly muscle. However, the low amperage (lack of power) does not have enough intensity to cause damage to the perpetrator's body unless the charge is applied over a period of time.
The electric charge of a real stun gun "disrupts" or interrupts the attacker's nervous system.
The following results could happen:
The charge of the stun gun can act synergistically with the electrical signals from the brain causing end tissue, such as a muscle, to contract continuously over short amount of time. The attacker will have a hard time telling is muscles to move in a different direction. This continuous contraction of the muscle will be hard to stop by the attacker due to the influx of an external charge provided by the stun gun. In laymen's terms, if he wanted to cease contracting his muscles, he couldn't because the charge provided by the stun gun is supplying the nerves that connect to his muscles.
The charge of the stun gun can exhibit a pulse frequency that imitates the body's own electrical signals. In this method, the charge from the stun gun will tell the attacker's muscles to do a ton of work, namely rapid repetitive contraction, in order to exhaust the attacker's adenosine triphosphate (ATP) in his muscle cells. ATP is the energy currency of all cells in the body. It is the energy of ATP that causes muscles to contract. The lack of ATP in the attacker's muscles will result in muscular weakness in the attacker. In other words, he will be too dazed and weak to get up after getting shocked.
The attacker has the same muscles and nerves throughout his entire body. Therefore, strategically placing the probes of the stun gun really does not matter in order to put down an attacker.
Note, however. Putting the probes of the stun gun in the attacker's stomach will not only cause severe muscular contraction in his abdominal (skeletal) muscles, but also cause the smooth muscles making up the digestive tract and the urinary bladder to contract as well. Simply put, you can cause your attacker to defecate AND urinate in his pants by the time he kisses the concrete!! YOU would have been a bad choice for this street punk.
