I gave up a life of drink & debauchery for cycling and later running, it was a worth while swap.

I'm not against drinking but there is enough evidence around to prove the harm it can do when used to excess. If i drink more than 3 pints it certainly makes me feel rough the following day and losing a day through alcohol is a waste of my time. It also makes for a cheap night out.

However - if people wish to drink copious amounts of alcohol, your choice.
