I won't bore you with the more general reasons about why I gave up as they are more or less the same as most other people's i.e. noticeable poor fitness when playing football, being skint but wasteing money, health, not wanting to die years before time, etc.
However one of my little additional extras that spurs me on came about through a very minor nag/arguement at my missus. Despite being in her early 30s she can't drive. She also steadfastly refuses to learn. I have had minor moans at her over the years we have gone out but it hasn't ever been an issue as we both live in Manchester.
However whilst I was nagging at her the last time she said she would learn to drive when I gave up smoking. Knowing that I had tried to give up fairly regularly and failed she also added the caveat that she would only consider it if I was quit for at least two weeks.
Well three and half weeks later all I can say is BROOM BROOM PARP PARP *skid noises* you'd better get some lessons booked
