One of the interesting things about Jujitsu is it's one of the really strenuous exercises that you can do late into your adult life, like into your 50, 60, 70s, 80s. When I came up, there's a few people in their 80s that were training. And as long as you're smart, as long as you practice techniques and pick your partners correctly, you can do that kind of art. That's late into life.
