I'm late 50s, overweight and unfit, and have mild chronic fatigue.
My commute is 3 miles. Too far for me to walk, but too short to be good for the car (and environment) in the long run. There is a bus, but it's half a mile walk at each end and takes as long as walking the whole way. Cycling is not an option at the moment.
Would it be crazy to buy an adult scooter for the commute? Not an electric one, a push-along one. It would give me some exercise and work my core while being less tiring than walking or cycling, reduce car use, and be faster than walking or bus.
