Uh, high school science teacher. Never really looked it up until today but considering there's science on the reverse effect (less oxygen for slower aging), I'd say it's probably not bullshit.

I don't get slot machines. They're not even slightly fun.
I wish casinos had fun games with small bets. Like, I don't know, poker where you can play several hands with 20 dollars.
But as it stands, I don't think I'll ever visit a casino again. It's either boring slots or you need to be rich to play the "real" games.
