I was 54 and had to give up many activities including 40 years of running, which nearly broke my heart. But the said as a young implantee, if I ran they would wear out too soon.
Now at 70, I walk and hike, dance, bicycle, Chase grandchildren, climb ladders, garden, just about whatever I want except run and jump not to say I don't play tag or shag an errant ball, just no sport running.
Small tradeoff for everything I can do.
