When I do that it just shows up in my mailbox again a few days later :/

Maybe I need to hand it to the USPS worker vs drop it in a mail collection box....

I was just wrote a zero knowledge architecture section of a whitepaper. For a second there I was so excited to learn a new, simple way to explain it... sigh

I'll add, if anyone would like to try something similar, but has trouble tolerating spicy foods, there's more than one way get your pepper fix. One is to make your own cayenne pepper (or equivalent) gel caps (capsule supplies can be ordered online and are +/- cheap, or do a cayenne pepper shot that doesn't burn your mouth. Just load up a spoonful, flip it to the back of your throat, then chug some water. Just be sure to not inhale between those steps :)
