Even zombies eat brains.
Babies cry when hungry. Piercing, persistent wails in the night.
Well, the assumption is that they're hungry. It's more likely that the baby is uncomfortable. If babies knew that what they desired was food, they wouldn't sometimes fight the nipple of a bottle or be fooled by a pacifier. Babies are notoriously uneducated.
At some point in my life, I realized that the uncomfortable feeling in my torso was a direct result of a lack of sustenance. Then I ate something. This is the foundation of my existence, the most important thing I have ever learned. Nothing is more important. Being a first generation college student with an unemployed parent doesn't matter. The hardships that I've overcome don't matter. The kittens I've rescued from fiery lakes of lava don't matter. (Seriously. There aren't scholarships for that.)
Unlike paddling lava lakes in kayaks full of kittens, eating isn't always easy. Every time I go shopping for food, I'm accosted by magazines crawling with women edited to look impossibly thin. Headlines are infected with fad diets. Every week a new food is bad. Strangely, last week's 'bad' food is never this week's 'good' food. The end result is that to women, all food is bad. Clothing sizes shrink. When the size -4 jeans that were bought last month fit just fine, but the new ones in the store are too tight, the message is to stop eating. The emperor's clothes are going to keep shrinking until women disappear.
But I'm a survivor. I eat when I'm hungry and sometimes I eat just because something looks tasty. I won't be told not to by any malicious advertising or hateful male designer, because I know the consequences. People who don't eat die, and dead people don't get to go to college.
