That's crazy to me. I had to quit my Very Competitive Men's Soccer League because I couldn't walk for 2-3 days after a game and that was a year or so ago still in my mid 30's. But same reason I decided to hang it up was due to having to play against college aged men that could run circles around me and I just couldn't fly as fast as them anymore without needed a long breather. Slightly different sports with non-stop vs play by play, but overall still takes agility, stamina, and determination. I miss it, but at the same time, enjoy walking and going up steps without pain and with a straight back vs bent. Hell, just getting out of a chair would sometimes be very painful until I was able to get past a certain point with my back. I literally had to start off crawling to loosen up sometimes.
Best of luck coming out of retirement. Jordan did it, I'm sure you can too.
