Sorry for the weird phrasing, English isn’t my first language.
I know men can theoretically have kids at whatever age, but there is still a limit to how old you can be to take care of your child.
I know someone who became a father in his late 70s (incredibly funny because when he and his siblings inherited things from their parents he paid them to get - I think it was a house - all by himself, they gladly took his money, thinking they’d get the house back anyway when he dies since he had no children at that time)
To each their own, but personally I wouldn’t have kids after 50. I know someone could be really healthy at 50-60 (sometimes more so than people half their age) but the body starts to kind of take its own course after 70. For me it would be more about the kind of quality time I could spend with my kids. I don’t want a teenage kid having to deal with a parent dying of old age or illnesses, which is totally possible if you have kids after 60.
