Eating Because You Can

We eat to survive. We eat to be healthy. We eat to sustain us. Sometimes we have busy schedules and need to eat a lot. Sometimes we eat because we don’t know when the next meal is coming. Eating just for the hell of it. Is another thing. Constantly shoving food in your face just because you can. It puzzles me. Is it really because there still hungry? Do they do it for personal reasons? I understand if it’s for personal reasons. But I do not understand is why they just eat and eat because they want to. Food is plentiful. But do we need to eat it because its there.
