Reel, 93, was celebrated during an event Wednesday for being the oldest active member of the facility in Vickery Village.His daughter, Linda, with whom he lives, drives him to the facility three times a week.“I bring him over here around 3:30 in the afternoon and he stays until 7 or 8 o’clock,” she said.Not only does he spend the majority of those three or four hours doing aerobics and lifting weights, he doesn’t cheat when going from the facility’s lobby to the gym areas. “My most impressive thing about him is … he always takes both flights of stairs,” Carithers said. “He never takes an elevator, and that’s a workout in itself.
