Lol if homie really had a stroke they'd want him on other anticoagulants besides aspirin, and if they wanted him taking aspirin at all, they'd really want it at 81 mg instead.

Wonder what other medical advice he's ignoring.

I mean, hopefully all of it and he runs his body into the ground like he’s trying to do with this country.

I had to be on high doses of aspirin and ibuprofen after an injury. I had to alternate them every 4 hours so I wouldn’t completely nuke my liver and I could only be on that schedule for a week. Doc said if I did too much all at once, or even just a standard dose all the time, it can kill you.

I always thought 81mg was such an arbitrary number. Why not 80?

Historic relic. The prior system to metric in medicine was the apothecary system and it used a standard called barleycorn as its unit. One grain of barleycorn was approx 64mg, and the standard dose of aspirin was 1.25 grains, or 81mg. Now 81mg hangs around as an in-joke.

Why is it 81?

Because of barleycorns.

It sounds like a bit.

There's a lot of stuff like that. In computer science, unexpected program errors are called "bugs" because the very first unexpected program error was due to a moth getting into the punch card system of an early computer.

QWERTY layouts persist in keyboards because they were copying typewriters. Typewriters were QWERTY to reduce the risk of colliding typebars by making common letters distant from each other, an intentional inefficiency.

Until 2001, US stocks were priced in dollars and sixteenth fractions, because the US stock system was based on the 1600s Spanish system, which used pieces of eight (1/8ths of a doubloon).

It's part of aspirin's legacy as one of humanity's oldest drugs. There's an old dose unit called grains. One grain = approx 64.8 mg. A full dose of aspirin is 5 grains, or 324 mg, and 1/4 of that is 81 mg.

Edit: what fox said.

It's 100mg in Australia
