It's called culture, and food is an amazing part of it. I wouldn't expect you to see the value in any of that though, since you seem to have hinged your existence on the joys of stuffing your face to the gills 24/7 and being a prick on the interwebs right from the comfort of your mom's basement.
Food doesn't have to be about being a fat slob. A well prepared meal is art you consume, and so many places on the planet have different specialties that should be experienced IMO. But hey, you're skiierman. You don't need that shit. Mom's meatloaf will be done any second (what does she even DO in there!?)
Sparknotes: Traveling is awesome, great food is amazing and you're an uncultured twat wrapped in an unwaveringly miserable douche.
