"no it doesn't"

Erm yes it does - that or the UK government has forced me to do a whole compulsory unit on the Nervous System and Caffeine etc.

It's because caffeine is a stimulant.

This stimulant stimulates the synapses - mean messages travel faster along the Central Nervous System.

It also causes blood to pump faster around the body - allow more oxygen to get to muscles speeding up the body's working time in general.

That's all I know...
