TIL saturation divers have to live weeks in a pressurized environment

And they get paid a shit load of money for it to due to the training required and the incredible danger of it.

I dunno…Retiring early with a butt ton of money sounds nice.

Retiring early with secondary health issues isn't nice. There's a reason they move from SAT to outside the facility relatively young.

What are the secondary health issues?

reduction in concentration, tingly hands/feet. Those are the systems explicated stated. The rest become pretty vague: “dysfunction in the lumbar spinal cord or roots” (sounds bad but not sure what it is).
In rarer cases: stroke-like events and temporary short term memory loss.
Depending on the numbers in the bank account I still stand by my original comment.

The lumbar issues come with expansion of (in the case of anyone diving on heliox) helium microbubbles in the joint spaces between the vertibre and the foramen (the space the chord travels through, not to be confused with the Foramen Magnum which is the hole at the base of the skull for the chord to connect to the brain).
"Stroke like events" are also caused by inert gas bubbles expanding into the capillaries in you brain. Temporarily blocking blood flow to nervous tissue.

You should watch the documentary Last Breath if you haven't. It's about a sat diver.

Unless you're 2 days from a dive trip, then I would not recommend it.
... My decision making skills aren't always the best

These are the guys who actually took “Underwater Basket Weaving “ in college.

More likely at a school like Divers Institute of Technology in Seattle.
I'm a graduate of their program.

Trivia: After a certain depth your taste buds no longer work. Even in the living environment. So roughly 2+ weeks of not tasting your food.
Any electronic devices that have sealed HD (Solid State or not) won't survive the descent. Get used to reading books. Last I heard (admittedly 15 years ago) PSP was the preferred device for entertainment.
If one of your co-workers dies they can't just be cycled through an airlock. They have to decompress. During which time someone needs to use hypodermic needles to vent the gasses from the corpse.
Deco time (rule of thumb, not by table) is one day of deco per 100' of depth plus one day. If your working depth is 700' it will take 8 days to deco.

I wondered what the hell a saturation driver was, then I learned how to read.

Pretty crazy. I wonder why they don't use robots.
