I went to an all night party in my 20s, drank a lot of beer, smoked 60 B&H (and a few other things ...), got about 10 minutes sleep, went home on a beautiful summer day feeling like death, collapsed on my bed, wheezing and coughing, saying 'never again', watched the men's singles final from Wimbledon, realised that those superb athletes were young men about the same age as me, decided that killing myself with bad habits at such a young age wasn't smart, and so ... gave up smoking! I decided not to do it any more, and so I didn't.
