  • probably not a good idea watching this at 2 am but oh well, it’s the sidemen; i feel like i have this off obligation to watch every video that pops up that i find interesting edit: ok a lot of these aren’t actually that scary but pretty interesting imo. they mention the fear of death in the the video but i think life is a lot easier when you just don’t care- like just live your best life without having to worry about dying or where you’re going after your life is over. bc like if ur just spending all your life stressing about what’s going to happen to u in the future, that can prevent you from living out a good life and it’s not really worth it tbh

  • 19:20 just for anyone who gives a shit the reason ants can lift a lot more than there own body weight is because they don’t have muscles, to lift things there legs work as almost hydraulics, using there blood as the liquid for it, so if they wanted to extend there leg then they would increase there blood pressure and it would extend, pull in a leg the lower the blood pressure

Actually happened to someone who woke up 5 min after dmt trip and said he legit just lived a life for so many years in his mind in dmt time which felt forever but in real time is only 5 min, he started crying and all that.

  • 0:50 Ok I’m in marching band and the video they’re reacting to is already stupid. As you know in (American) Football there is a booth that is on top of the bleachers (behind the top row of bleachers) and usually you can access the roof of it (in marching band we call it “the box”). That’s how they get the camera angle for marching shows. But since it’s a college stadium, they might not have to be on the roof of the box and able to be on the bleachers, usually sat on the steps. Or they could just use a drone as well

  • Most of these theories in the video aren't experiementally tested, they are just hypothesis. When an hypothesis is tested through experiement and observations, it is then called a scientific theory, this video guy is full of shit that doesn't know nothing about science.

  • I understand what vik is talking about when he said "ik I'm real but idk about anyone else" I also think of this, it makes me paranoid. I also feel like if someone agrees with me about this theory that they're trying to put me off the thought so I don't find out the truth. But hey that's just a theory, a game theory.
