2. Eating out is the only way to survive
It might sound less conducive to a healthy diet, but if one wants to keep surviving from day to day they will eventually learn to pick a favorite place or several places to go to eat each day and night. With limited space and little if anything in the way of a kitchen you’ll quickly learn that eating out is the best way to keep yourself fed. While it might promote more waste and become another expense, at the very least you won’t need to worry over an exorbitant grocery bill. Plus, all the exercise you get by taking the stairs up and down is a good way to burn off those calories.
