I would like to be younger again, not in my teens maybe early 30's to late 40's. I always feel at that age you old enough to do everything and still young enough to enjoy doing it. PS I will be 76 next month.
Personality-wise, I'd say no. Part of me wants to say yes because I'm curious what it would be like to be less introverted with face-to-face conversations, but then the introvert in me reminds me that I'd be socially drained lol.
Financially, yes, but I think this holds true for most people haha.
