I hate the term "past their prime"...these guys still have the talent and the 'it' factor

I have no problem seeing a guy, or girl, who is no longer in their physical prime doing what they love or doing what they are trained to do.  I know that after age 40-45, one's sight is affected and the body begins to slow down as compared to someone who is in their 20s especially.  But with all of us, aging is just a state of mind.  I wonder that to be true.  I hope to be living long enough to see these fighters, actors, and entertainers over again, because these performers show us younger people that they "still got it".  These performers remind us that even though our bodies age, we can still be young at heart and youthful in attitude.
