I quit 23 years ago at my sons christening "reception tea" in my local pub ..handed an almost full packet over the bar and said to give them to the next person who wanted to buy some ..
I hadnt really planned on it ..but I'd realised that if I continued smoking at the rate I was going I may not be around long enough to see him become a man ..
(about £4.00 for 20 back then ..)
I was 46 years old at the time ..and would even have a fag while out mtb'ing ..
Havent touched one since ..but strangely Ive always said that given the chance Id have one just before I croaked
