Correct,you are a long time retired. Yes you might need to drop down levels as you get older but nothing beats playing. If you love playing the game then moving down as you get older is not a problem.
I know somebody who plays for the over 70s England walking football team.
That’s my long time aim. Win the World Cup at 74!
Walking every day for 90mins with 25kgs + on my back building up that walking power for the next 20 years!
Move like Jan Molby in his prime!!

I can actually start to play walking football next year. I’m considering it!!
