This is my view on things. When we're younger we try more things because we don't recognize fear as much. The older people get the more they fear the unknown. Sometimes it's more fun to slip into that younger mindset and forget the fear and just live!
Try, even if the chances are incredibly lowered than they used to be. Maybe you'll get lucky. Maybe not. But at least if you try, you will die knowing that you gave it your all rather than giving up a long time before the fight has even begun.
