Caffeine

American Parkour just came out with a statement that they won't support Red Bull's extreme sports Parkour division because of the amount of caffeine inside of the drink.

This raises the question how bad is caffeine for you?

Caffeine is a central nervous system stimulant, it is usually used to fight off drowsiness. It speeds up the heart rate

and can make pain killers 40% more effective.

Caffeine and parkour don't mix though. Once the caffeine enters the blood stream it starts to throw off balance, can start tremors in the muscles, and blur vision. Any good tracuer knows that any of these can be disastrous and harmful. Sense of balance can make or break a jump and the caffeine compromises that. 

So I say it was a smart move for APK not to support Red Bull. Any drug that can do that much harm to your body shouldn't be taken.
