Watch: Ultra 80 tennis. The nation’s best players 80 years old and up.

Another interesting tennis-focused Kickstarter campaign just hit my desk. These tennis players/gentlemen covet gold balls and are going for record numbers of them.

"Your only as old as you allow yourself to think you are." says John Powless, the USA's #1 Ultra Senior Champion. His tennis regime borders on religion. Injuries and reconstructions be damned.

Check out the GoldBallsMovie campaign. 4 days to go today. Make this happen. I want to watch it. These men are impressive.
