I first heard myself say “argh!” some five years ago, when I bent over to tie my shoes. I might not have noticed it, but there was someone else there, older and wiser than I, who recognized it immediately and pointed out that this is a sound that people make when they get old. I now keep an accounting of how often I say “Argh.” It’s punctuating many of my activities. This evening, I was laying on my stomach watching a film and got up to fetch a bottle of saké. While I was rallying against gravity, with old bones first folding and then unfolding to allow me to stand on two pins, I said “ARGH” at least three times.

So, watch out for this sound, it’s a dead giveaway.
