My hero story is a 90+ friend that takes his adult tricycle on 30+ miles rides. He was always in great shape riding 200 miles on his birthday. He had an unfortunate layoff but got back to it when he could.
My Hero is my Mother. At 90 she was still doing burpees and bearcrawls. At 91, she still swims 3-4 days a week and works with her personal trainer 3 days a week (I think she gave up on the burpees last winter).
