My dad is turning 36 in April, and quite a few of my friends (I’m 18, for reference) say that he doesn’t “act his age.” By that, they mean he posts a lot on Instagram (especially daily Stories where he vlogs his life, lol), he’s trendy and very open-minded, works out and takes great care of himself so he looks hot, and he’s really into nightlife and partying. He’s also very adventurous and just a fun guy in general. They don’t think it’s a bad thing at all - in fact, they think it’s cool. But it got me wondering: how is a 36-year-old supposed to act? lol
Old really is how you feel. I feel old now (48, going on 49), but only because of how my life turned out and certain events that I have to deal with (divorce, single fatherhood, getting colonoscopies, etc) by myself. I certainly don’t have as much fun as I used to, and that definitely plays a huge part in feeling old.
All that to say that if your dad is having fun, “not acting his age”, then good for him! I hope he gets many more years of that before shit has to get serious.
To directly answer your question: a 36-old is supposed to act however they want to (within moral reason of course), so long as they and the people around them are enjoying it.
