Some sports are naturally of Olympic caliber.
Basketball, swimming, track. An argument could even be made for the hammer throw. The same medals that were given to athletes like Mark Spitz and Jackie Joyner-Kersee will be hung around the necks of people whose sport is offered as a class at nursing homes. Make it like the decathlon, with couples switching dances styles every time the music changes. At least that would be funny, would provide some sort of amusement.
