We just have to do it.
Gnawing on food and freezing your throat with drink is an excellent way to pass time. It also shows a level of humanity. Only robots don't eat. Aliens from District 9 don't count either; all they eat is cat food.
So are there any advantages to not eating? Lets find out.
- No Interruptions: Our bodies clear out waste at odd intervals- which is normally the food we remembered to eat. Whether number one, two, or even four have entered your body's payroll; they will find a way to disturb your schedule. Say your trying to hide and a fart pops out from that lunch of tacos. Is that a good situation?
- Speaking of Interrogations: A villain will most likely let you go if you look pathetic enough. Starving men can act... The point is however, evil masterminds don't want to waste resources or time. So they want a challenge anyway. Just for the fun of it. A man who can't pick himself up is no challenge. Case in point, is free with an apology, a cup of coffee, and maybe a slice of pie. Don't forget to add the cherries.
- Drool, Drool, Drool:
Or you could embarrass them long enough to escape. It depends on how much they care for their clothes.
- Feel Good: Eating makes me feel good. It also makes others release stress. So let the hero have his food, at least he can be in a good mood about it.
