And you're better off for it.I’m the same way but from seeing how that and drugs affected friends of mine I’ve known since high school.
Never smoked or taken anything and only drink on special occasions.
Have an uncle who's still alive and in his early seventies. Used to be built like an absolute ox in his prime, based off the pics I've seen of him in his youth. Kind of guy nobody would want to fuck with, if they had a functioning brain, given he was over 6-feet, and looked like a cross between Samoa Joe and Brock Lesnar, and was still built like a beast during my childhood, when he was in his fifties, even, just to a lesser degree.
All that alcohol abuse caught up to him eventually though, and when he hit his sixties, he lost a frightening amount of weight due to a surgery he had to go through, because of how badly damaged one of his organs was from all that alcohol, and since then, has looked downright emaciated. Barely able to walk anymore, and but a shadow of the man he used to be. Has to be in a home now, the poor guy, because he can't effectively look after himself anymore, and my cousins don't have the time to look after him, either. A damn shame, I tell ya. He was one of the coolest and funniest guys I have ever known. Never failed to make me laugh or scare the shit out of me, when he'd mock charge or chase me around the lawn for the fun of it.
Nowadays though, when I last got to visit, there was hardly much of that life left in him, when we spoke. If anyone's a cautionary tale of how destructive alcohol can be(though there are certainly worse examples out there), it'd be him.
