Yes* but with caveats. Not in the house and not in an enclosed space. That's how you get a smoker where you can't tell they do since they're not standing in it.

Mouth hygiene would be more important. Don't like kissing smoke mouth. Can't be too many a day. I'm okay with a steady habit like one b4 work 1 after work. A few more on days off. You lack discipline with the addiction and edge closer to pack a day, I'm out.

I used to so I get why someone would.

I don't think I'd really be all that concerned about the day to day life at some point. Eventually you'd be living off the interest of your bank accounts. So just work until that's going for me.

I think I'd try and live in every single country. Enjoy as much as I could.

Then float idk. Actually probably not. I'd most likely fall into the red giant sun and roast there until it BRAPS the rankest fart ever and then I'd roast in a white dwarf. Then maybe I float after however long that takes to evaporate as I watch the universe slowly go dark erasing everything and everyone there ever was.

Maybe a fresh big bang would finally end me or a black hole. Fucking gravity wells are such a drag.

Not rare, my country barely owns anything in it including the media.
