Don’t get me wrong, if I had my choice, I’d choose to fly or have superhuman strength or something like that. But at the moment, as a student, I think I’d like the ability to eat endless amounts of food at parties, potlucks, etc. Then I’d like to be able to either store the calories until I needed to use them, or to somehow be able to re-eat the food later, when I needed it. (i.e. when there wasn’t free food.) This would have to be more elegant than the momma bird regurgitating food to its baby bird. Maybe the food would just appear in my fridge.
Alternatively, some sort of magic tote bag in which I could pack unlimited amounts of food, which would never go bad. (Sorta like that drinking horn that Thor tried to drain, but it was actually connected to the sea.) This is less ideal, however, because it’d be real rude, not to mention conspicuous, to swipe plates of food from parties and empty them into a bag.
More practical, of course, is regular income.
