Started drinking before 10 (if by that you mean drinking wine "socially" during Christmas, my birthday, family dinners, when something good happened*, etc.)
Never smoke, don't want to try even.
I only drink socially now, or when I want to congratulate myself. I guess if I drank often, it wouldn't be that good.
* Though one time I had to drink after a funeral. It felt really weird; the person would have wanted us to stay happy but it still confused me at the moment.
