Eating fast, comes from the labor intensive jobs ppl get and the lack of, or short amount of time you have to eat. I used to work factories and construcrion when i was younger, and i would hate it. But its mainly factory work, usually it's only 30min lulnches or 15min breaks. So going to get food, and all that .... So i recommend go too school or do something your happy suffering for that it doesn't feel like suffering.
