For me I really do enjoy watching some of the Locking picking lawyers content and he is an expert when it comes to picking locks!
Another few are mental outlaw (although I think everyone knows of him here) and Steven Bridges who makes videos on card counting at casinos and he shows how much he wins/loses from playing
I discovered a channel called ‘Just Alex’ awhile ago, and I’ve binge-watched most of his videos. He makes videos about a variety of activities he engages in. For example, two years ago, he started beekeeping as a hobby. In these videos, he shows the progress he has made since then, taking care of his bees and harvesting their honey.
He also has videos on collecting mushrooms, growing crops, and traveling around Europe.
What I like about him is how calming his videos are and the amount of effort he puts into making them interesting, without resorting to clickbait content.
