I know some ultra-marathoners, people who work extremely hard at heights, skateboarders/parkour...ist?/rock climbers, and one semi-pro soccer player who has a vertical leap that is unreal. Their connection is that none of them have social media(I dont count lemmy and do count 🦣). They are all capable of some amazing things that make you rethink humanity a bit. None of them look like instagram models, but I would argue that they are all more fit than the insta model crowd. I wouldn't be inclined to bet on the models in a 1v1 fight either.

TLDR: I think the batman bit is more realistic
