22 yo Husband Saying That He's Old 😂

I think my husband has lost his frigging mind. He just gave me this whole spiel on how his clock is ticking, he only has 8 more years until he's 30 😂, and he is getting to be an old fart. I said dude, you're only 22... he goes you better start enjoying 21 while you can because when you're 22 you'll feel the same way. Any one else's husbands who are young feel this way? Where the heck did this come from? How do I make him feel that he is a youthful fruitful man?😂 Our birthdays aren't even until October?!!
