You gave up smoking when you were 12 ??? Wow, most people that smoke would not even have started by that age...
Apologies if it is too much of a private question, feel free to ignore: At what age did you start ? Were your parents aware ?
10; parents, probably though I thought not at the time - it wasn't exactly a big habit, probably like one a week! Just one of those things one does to try and be cool and fit in. Then I realised it's stupid. I was probably a little under 12 then.
My mates folks owned a pub, his parents definitely knew we were getting our fags there.
I was speculating whether or not computers make me overall less productive or not - I'm convinced they do. I need other people around to work with, then I can get "addicted" to helping and progressing the task rather than anything else.
Sadly I'm working largely autonomously despite efforts to change that.
