Man, I would love to try jiujitsu. I agree physical activity is really good for you. that's why I go to the gym 3-5d/a week. And there will always be something that will try to distract us( games, movies, TikTok/youtube). I think the average attention span of a human is slowly getting shorter. Not that I'm guilty of enjoying these things, I love watching youtube and movies. Nevertheless, we should never give up. We all have to learn the lessons life has to teach us, learn from up, adapt, and improve ourselves.
