Just donated blood today to shed some iron and it occurred to me how every medical system always needs blood, they're always out there begging for it, and yet at the same time people need blood tests, and in the US at least they cost a fortune. Why not if you need routine bloodwork, you just pop in donate a pint, and they take the first vial full and process the bloodwork? Every blood drive should offer free HBA1C, triglycerides, insulin, HDL, vitamin D, etc. Two birds one needle.
Was thinking about time and how we know whether one event preceded or followed another. Like there’s nothing axiomatic about the words on this screen succeeding my typing them. I could dictate them and type them afterwords for the hell of it. But in some cases we know what came first and what came second, for example, a whole egg and a splattered one. The whole egg MUST precede the splattered one. The splattered one can never reassemble into the whole. That’s because the splattered egg is more disordered (has more entropy) and the arrow of time is essentially increasing entropy. But biological systems in some ways undercut that because while it’s trivial to grasp the whole egg came before the splattered one, it’s hard to say whether it came before the chicken.
