Find someone else in a chair and have races. That is what I did in the hospital and drove the nurses crazy. When we got crutches we raced with those and learned some tricks too. But I was younger then and around a bunch of other crazy guys with no wife or family to worry about me or me to worry about. Just get yourself a good pellet gun and drop some squirrels then have your other half go get them and cook them

Arrows would be fun too just use judo points so you lose fewer arrows.
