I like it too…I’ve always wondered if there are things we can sweat out that we can’t pee out. Urine is actually a pretty complicated fluid.

One weird but true medical observation: people in chronic renal failure look older than their stated age. When they get a renal transplant, they start looking considerably younger.

Conclusion: there is something in urine that makes us at least appear to age…something dialysis can’t get rid of. To my knowledge, nobody knows precisely why this happens.

fascinating. this might bug me for the rest of my life lol. would be interesting to put someone in renal failure in sauna (to tolerance) and test their sweat. do you sauna? I know I feel better esp when paired with cold after. the sharpest 80 yo i know (is still a lawyer for trump) saunas daily.

I don’t sauna, but I do live in a desert. I mean, that’s gotta count for something.

Any fluid that comes out of the body has the potential to remove harmful substances. I wouldn’t reject out of hand the benefits of sweating, spitting, crying, lactating, vomiting, etc…there are even medicines to promote the excretion of bile via the gi tract.

Maybe I’ll get my CSF replaced every 100,000 miles just to be safe :)
