Is being called Old an insult?
I did hit 65 3 weeks ago. And yes I do have my aches and pains but I guarantee that when the adrenaline hits I don't feel any pains and muscle memory and training from the past definitely kicks in.
I consider it a compliment... I usually look at the other person, and let them know that I made it to being old (~43) and let them know they may not get there themselves.
