I wonder about these questions a lot! I can also see a very logical extension to GLP-1s - as a fat person who is not interested in those medications, I’m starting to see subtle shifts from pity to confusion about my size (if she has money and health care, why ISN’T she on a GLP-1?).

i've half-joked about how you aren't actually rich until you have "cancer money", or enough that you can pay for treatment *and* be out of work for however long *and* maintain your or your family's basic quality of life (ie, not having to liquidate core assets like your primary residence).
