A very serious MPP that I'm posting here as a sort of PSA, since I've seen people talking about it on this forum a number of times.
An acquaintance of mine - a previously healthy man in his early 40s - started having some problems out of nowhere... he fell, he couldn't figure out some app on his phone that he uses all the time. Odd stuff. His ex took him to the ER because she thought something was really wrong with him. Long story short, he needs brain surgery (best case scenario) or months to years of radiation therapy (worst case). Guess what? He's a really frugal guy. So frugal, he opted out of his employer-provided health insurance plan so he wouldn't have to pay the premiums, even though he has a good job that pays well. Zero medical coverage. Not sure what he's going to do. :-(
