PANTS
Einstein wore the same outfit everyday of his adult life. Not because he was a big weirdo (although he totally was), It was because he found the perfectly comfortable pants/top combo ever and never had to try anything new ever again.
That’s what they saved his brain after he died. To see how an advanced mind was able to find perfection in the mundane!
I’m not saying they’re going to study my brain after I die, but I wouldn’t be surprised if the children of the future will one day see an exhibit of covid-era sweatpants in the Smithsonian and notice my name on the plaque.
