A lot more shoulder and knee injuries playing tennis so I’d like to Thank pickleball for the alternative competition. So true, between my hubby and me, 3 titanium knees, One shoulder replacement, two titanium plates holding down Achilles tendons and the beat goes on. I run tournaments and trust me…. I’m not getting rich from it. It’s a ton of work and a lot of money goes into various things like medals (spent over $400 last week on ones for one upcoming tourney) plus gym rental, equipment and of course time.
