Slightly related - I when to the doctor’s with a suspected UTI, which turned out to be nothing serious. During their scan they discovered that I only have 1 kidney. I was shocked, but they explained that it’s more common than you might think and that my life expectancy/quality would likely be unaffected. I was 47 at the time and drank pretty hard in my 20s. Zero I’ll effects, but definitely unsettlling. Annoyingly I made the mistake of telling a friend immediately after the diagnosis. I live rurally so now a bunch of people know me as has the guy with 1 kidney, which sucks.
