Energy At Any Age

Yesterday, I passed a gymnasium filled with crazy happy Dodgeball players. This was a game I played in my youth where the object is to avoid being hit by a ball from a player. The players were mostly young people, mainly seemed to be hit by the ball, and the game ended fairly quickly. I thought to myself how good I would be at this game, since the object is to dodge the ball, rather than stand their like a sleeping duck in a pond.
As I looked closely at the players, I noticed that the age group was mostly twenty-something. It appeared that those older than the players were either sitting at home watching television, doing those tired and expensive yoga poses, or just plain being sedentary.
It's wrong to be so plain sedentary. Exercise is something special and should be cherished at any age.
But why are so many things so beholden upon youth?
I believe that times are "a changing" and a new movement will take place where doors will be open to older people, who should be able to do anything at any age.
Bryan Adams sang a song about "Being 18 Til I Die" which is a good song becauses it basically emphasizes that trying something new is for everyone and the joy of doing things, the boundless enthusiasm, whether it be for learning, travel, new hobbies, should be extended towards all, regardless of one's age.
