They are definitely things that go together.
Not in a serious way I would say.
Play professionally, different from play for leisure, even involving money.
Playing for fun with lots of smoke and good old whiskey never hurt anyone.
Of course, cigarettes and drinks are not healthy things, but as a great Brazilian song would say:
'I drink yes I'm living ....There are people who don't drink and it's dying' lol
I tend to think that I perform normally, but that's obviously not true. But as already mentioned it is fun.
