Years ago, a friend got deadly ill with cancer and had to undergo chemo and radiation therapy. Eventually, he had to stay at the hospital for a few months. His immune system was weakened and he was at risk of infection and before he could return back home he needed someone to clean his place. I and some of his other friends volunteered and we cleaned up and sanitized his place. Among the things we found was a repurposed orange juice plastic bottle filled with urine and in the freezer was a large mug filled with what looked like some kind of disgusting pasta sauce. As it later turned out, this was actually vomitus. When my friend was still at home and feeling so ill he had a hard time getting up and going to the bathroom, he simply peed in a bottle he kept on his desk. The vomit ended up in the freezer because after throwing up in the mug that was in reach, he had to let a handyman into his place and the fridge was closest. So he cryogenically preserved his vomit. He's much better now and in fact, he's back at work.
