Aruko takes absolutely zero care of herself beyond managing to live, while Yaku mostly just uses the drugs to cope with her high stress and is shockingly healthy because she actually goes about trying to keep herself together.
Nah more like, everyone definitely will throw up eating undercooked expired chicken combined with sprouted potato.
I have weird habit of eating expired stuff including badly sprouted potato (which of course I got rid of the sprouts) thinking "haha as long as I won't have to be rushed to ICU it's okay", but even I, as reckless as I am, AVOID UNDERCOOKED CHICKEN at all cost.
