Tsuyu, being the fervent capitalist I am, I see several money making ventures that could come of this "disorder".
1. Get a job at a zoo. You could help feed penguins by cramming fish down your Norse gullet, digesting it, then vomiting it into their mouths like so:
2. Food critic. Go to restraunts and eat. Then excuse yourself to the bathroom, vomit, and go back for more.
3. Chicha maker. Chew corn, swallow it, throw it up into a vat, let ferment for a few weeks and you have CHICHA! The yummy beverage beloved in Amazonia.
Mmm! More chicha please!
