Stress
You live with 99 other men for three months at a time, with 15 square feet to call your own. You go for long periods of time without seeing the sun. You lose track of what time of day it is… if there even is such a thing as “day” anymore. That’s stress, my friend. Soul-crushing, mood-altering stress.
And you can’t even binge-eat the stress away… because what are you going to eat? Canned baby corn? Kidney beans? That will just make you go all Captain Ahab. Or Captain Nemo. Boat captains never fare well mentally… Take that as your warning.
