It's not really reliance on wheels, but reduction of all mechanical work as one then goes to sit at a desk. Walking a 60km commute every day wouldn't be good for your knees either though. > will lead to bone density loss and muscular dystrophy. It's not right to call this bone and muscle distrophy. Not playing squash, probably the sport leading to the highest bone density by far, does not mean you suffer from or muscle distrophy. Rather, whenever you change any habits, your bone density and muscle mass adjusts to prioritize things relevant. Pick up tennis? Your right arm will be heavily prioritized. Change to running? Your arms will no longer be prioritized. It's mainly an issue when you drop below a healthy limit - that doesn't really happen from changing your exercise, but from a complete lack or physical disorders. (Suggesting one is "cutting out" walking or jogging once they get tied to a wheelchair might also not be the best way to phrase things.)
