Have you ever heard about the Tham Luang cave rescue?
In June and July 2018, Twelve members of a Thai junior association football team (soccer in the US), aged 11 to 16, and their 25-year-old assistant coach became trapped in a cave in northern Thailand. Shortly after they entered, heavy rainfall began and partially flooded the cave system, blocking their way out and trapping them deep within the cave system.
Several cave divers decided to venture miles into an underwater cave to attempt to rescue each one of the members by putting them under basic anesthesia and dragging them out completely underwater.
After watching this documentary from National Geographic, I can say with confidence that the divers who went into that cave have to be some of the most extremely fringe minds in the world. To dive those caves in good conditions would be incredibly difficult for most but that they did it in the most intense conditions AND with another human under basic anesthesia.
That's absolutely mental.
Here's the trailer for the documentary

They also made a dramatization about this but I've never actually seen it. It's on my list but will take some time for me to find the time to actually watch it. It looks pretty good.
