What difference does that make?

There's a river goes thru london which seperates on side from the other but they speak the same language...........sorta........and Ireland.......and again they speak the same language............cept for where they don't

Also there's a big puddle in my drive seperating me from my neighbours and we still speak the same language

Besides, Canada has strong ties with Britain

Edit: You do realise I'm just arguing for the sake of it now?

Medically, caffeine is useful as a cardiac stimulant and also as a mild diuretic (it increases urine production). Recreationally, it is used to provide a "boost of energy" or a feeling of heightened alertness. It's often used to stay awake longer -- college students and drivers use it to stay awake late into the night. Many people feel as though they "cannot function" in the morning without a cup of coffee to provide caffeine and the boost it gives them.

Caffeine is an addictive drug. Among its many actions, it operates using the same mechanisms that amphetamines, cocaine, and heroin use to stimulate the brain. On a spectrum, caffeine's effects are more mild than amphetamines, cocaine and heroin, but it is manipulating the same channels, and that is one of the things that gives caffeine its addictive qualities. If you feel like you cannot function without it and must consume it every day, then you are addicted to caffeine.

That explains the pissing every 5 mins

Caffeine and Adenosine
Why do so many people consume so much caffeine? Why does caffeine wake you up? By understanding the drug's actions inside the body you can see why people use it so much.

In the HowStuffWorks article How Sleep Works, the action of adenosine is discussed. As adenosine is created in the brain, it binds to adenosine receptors. The binding of adenosine causes drowsiness by slowing down nerve cell activity. In the brain, adenosine binding also causes blood vessels to dilate (presumably to let more oxygen in during sleep).

To a nerve cell, caffeine looks like adenosine. Caffeine therefore binds to the adenosine receptor. However, it doesn't slow down the cell's activity like adenosine would. So the cell cannot "see" adenosine anymore because caffeine is taking up all the receptors adenosine binds to. So instead of slowing down because of the adenosine level, the cells speed up. You can see that caffeine also causes the brain's blood vessels to constrict, because it blocks adenosine's ability to open them up. This effect is why some headache medicines like Anacin contain caffeine -- if you have a vascular headache, the caffeine will close down the blood vessels and relieve it.

So now you have increased neuron firing in the brain. The pituitary gland sees all of the activity and thinks some sort of emergency must be occurring, so it releases hormones that tell the adrenal glands to produce adrenaline (epinephrine). Adrenaline is the "fight or flight" hormone, and it has a number of effects on your body:

* Your pupils dilate.
* Your breathing tubes open up (this is why people suffering from severe asthma attacks are sometimes injected with epinephrine).
* Your heart beats faster.
* Blood vessels on the surface constrict to slow blood flow from cuts and also to increase blood flow to muscles. Blood pressure rises.
* Blood flow to the stomach slows.
* The liver releases sugar into the bloodstream for extra energy.
* Muscles tighten up, ready for action.

This explains why, after consuming a big cup of coffee, your hands get cold, your muscles tense up, you feel excited and you can feel your heart beat increasing.

That explains the rest
