It’s right there in the name - Mr. Beast.
I wouldn’t seek out a personal trainer who chooses the name Mr. Hyde personally.
Play stupid games, win stupid prizes - the $500k isn’t stupid, but the psychological effects are forever. Hope some of that money got earmarked for therapy and counseling! Not kidding, I am an advocate for CBT and I’m pretty sure this situation is pretty similar to stories where lottery winners end up with mo money mo problems.
