Mine is this little tidbit about Khaki’s from https://www.heddels.com/2019/05/history-khaki-anything-drab/

“Tried and tested by all the major powers, khaki-dyed, lightweight cotton twills became the de facto uniform for any colonizing power. If you were going to ship your boys abroad to pillage and conquer someplace in the Southern Hemisphere, khaki was your go-to color.”

    Not really a secret, but we don’t often think about it.

    Cash is fucking dirty. Here is the official Fedral Reserve estimated lifespan for each note:

    Denomination Estimated Lifespan*
    $1 7.2 years
    $5 5.8 years
    $10 5.7 years
    $20 11.1 years
    $50 14.9 years
    $100 24.0 years

    You can assume that something like a $5 bill might change hands on a weekly basis.

    So if you a $5 bill that still looks nice, it might be only 2 years old, so it might have seen about 100 owners up until now. It is said that 1 out of 5 people don’t wash hands after pooping.

    Your $5 bill is probably filled with poop, pee, sweat, food, cum, dirt, etc.
