So many men age themselves out of the game. They refuse to do things they want to do because they feel as if they're 'too old'. It's not only ridiculous, but it is a form of (mental) self-harm. Granted, your body shifts and changes as you get older, but you don't have to shuffle creaky into that dark night.
You can get older, without becoming old. You can be youthful, without being young.
