Here is what nobody tells you when you retire and pick up pickleball.
Thirty or forty years sitting at a desk leaves your tendons stiff, weak, and starved of blood flow. Then you retire. You find pickleball. You love it. You play four times a week because you finally have the time.
But your tendons were never warned.
Every single paddle strike sends vibration up your forearm into the tendon. Hundreds of times per session. Your tendons — already weakened from decades at a desk — absorb every single one.
The sport did not warn you. Nobody warned you. You just wanted to play with your people.
