I'm not as old was you breh but I'm in your same situation. I'm retired and other than remote managing my Airbnb's and my investments I don't spend as much time on hobbies as I would like during COVID. I would advise to you get out more, either in the region where you live or overseas. Live a little and get out the comfort zone of corny chicks around your way.
Recently losing those 60 pounds I picked up since I retired wasn't a bad idea neither. Now I'm getting very young women checking me out again, which may make things worst if I'm not careful. I didn't realize how many young girls had stopped checking for me...lol. Btw, it was only one chick that had a problem with my lack of hobbies, and she was the prettiest of them since I retired...it figures. I didn't even hang around long enough to nail her, but if I had, I'm sure my lack of hobbies wouldn't have been a problem with her anymore. But she had way too much game with her, and when you get my age, you suppose to know when to bailout, even if means not tapping it when you could have. With the rest of the chicks, although there wasn't all that many, it was more of a "What did you do all day?" type of thing with them, who were basically jealous because they still had to work all day. But a lot of people in general had that same jealousy issue too, and some were close friends and relatives, as you probably found out yourself.
Yes, I do plan to go overseas a few more times, even thought about relocating over there. But like you said, that COVID stopped me in my tracks, not to mention the horror stories I've heard happening to brothers, like the brother from Atlanta who recently relocated to Colombia and got robbed and murdered. I still remember what happened to those two elderly sisters from Detroit, who got murdered with a hatchet after relocating to Ghana. I was like one month from relocating there, until I heard about that. They even poisoned and killed their two dogs a week before. Tbh, as I've gotten older, and although I still wouldn't mind traveling overseas after the coast is clear, I feel a lot more content with my life. I didn't realize how much joy you get from hearing the children's laughter next door, the smell of grass, a nice walk in the park followed with a little weight training every now and then, kicking it with an old buddy on the phone, eating good food (very important), looking at the women without going crazy, having a little pizza and bbq chicken on a weekend with a beer every now and then, catching a good movie here and there, checking out my you-tube videos, going outta town to see family and friends without worrying about getting back on time, the list goes on. I took these small things for granted over the years and didn't even realize it. Most of the joy come from within. I didn't just get here overnight, and some brothers older than me don't get to this point at all. No way am I'm trying to blow this on some random chick. Plus they can still get pregnant. In fact every chick I laid with since I started working IT tried to get pregnant, and that was before I had everything paid for and retired. Paying child support for 18 years to a girl you didn't even like mentally, like I had to when I was 19, and not having the best relationship in the world with your own child because you and your child didn't grow up in the same house, makes it easier to chose between being stuck for another 18 years paying child support to another lose girl, and finding out what really brings you joy, even if it means staying single.
Btw I'm looking more into hosting Airbnb too, to help me travel. So far everybody is warning me against it. But these are people who really have no experience with it.
