Flogging a knackered horse, metaphorically-speaking.

Q. What do you get when you flog a knackered horse?

Coffee is a Central Nervous System (CNS) stimulant. A coffee first thing in the morning after getting out of bed gives you "get up and go". What happens if you carry on drinking coffees or "Energy Drinks" throughout the day? Guess!

Coffee and brrrup-brrrap!

Here's some soothing music for those of you who are "coming down" from caffeine or any other stimulant.
