How old do you have to be before you no longer give a rip about what anybody thinks if you let out a yell every time you commit to a minor physical strain?

I was behind this guy who might have been in his 70s in a grocery checkout aisle this afternoon. He dropped a penny. I would have reached for it but I was holding my bike and it would have been an unwieldy maneuver.

Anyway, when he bent over to get the coin he let out a yell. A loud, raspy one. It seemed like a sound one might associate with crocodile attacks.

I could tell from his face that he was fine and had not suffered an injury. The vocalization was just part of his exertion routine.

So, assuming relatively normal health and mental well-being, how old do you have to be before you are apt to feel OK about a similar lack of self-consciousness?
