Speedo Limit?

speedo_handstand

Is there age that men should stop wearing Speedo style swimmers at the beach or pool?

Is it that at 40 and overweight (seemingly normal),  the board shorts just don’t look as bad, or is the Speedo look just for younger people?

What if a man at 60 is in good condition? Are Speedos OK for him?

Also when should we stop doing handstands and cartwheels and “act like grownups”?
