In one of my random You Tube binges I discovered this show called "Mind Field." I'm not a You Tube Red subscriber, but an ad for this show popped up and it seemed really interesting. Plus they're offering to watch the first episode of season 1 for free.
Free is always good.
Although as good as this show is, I might start to think about subscribing to check out the content. This is not a paid advertisement, FYI. I was just really drawn in by this show. I've only gotten a hint of what the content for the rest of the season, but it appears to be all about how the mind works.
The first episode dives into what the mind does when there's no external stimulus, and the host (You Tuber Vsauce) puts himself in isolation for 72 hours. It's worth a "look-see."
