this sounds very funny and all but a 22 year old would normally have a father of like 47 - 60 years of age which is less than optimal in my opinion. not saying that i don't personally know at least one very hot 50-year old man but like ... old men in general = ugh.
A lot of that has to do with your age and how well they take care of themselves. If I was in my 60’s I would definitely find Patrick Stewart attractive and he's 78. Hell, Robert Downey Jr is 53 and Keanu Reeves is 54 (I'm 30) and I'd jump on that in a heartbeat. (If I wasn't married) Also, a 22 year old could have a father quite a bit younger than that. 40 if they had the kid at 18.
I can sense some crisis there that will lead to “You are not the father!“
