Illiteracy and Obesity

I've completed some highly scientific research that has revolutionized my perspective on obesity in North America:

I'm functionally illiterate right now (there are three different alphabets in the Japanese language!!) so as you can image, grocery shopping is functionally challenging. Since I cannot read what I'm buying, I generally have to stick to stuff that's in similar packaging to products at home or I have to go through the process of trial and error. The error part is not fun - last week I thought I was buying peanut butter, it turned out to be some sort of weird sweet peanut jelly. So, if one is out and about, and hungry (as one often is) stopping into a restaurant poses a problem. Either you need someone who can read Japanese with you, or you need a restaurant with pictures on the menu. Yes, the latter is common, but the menus with pictures are often only at the cash register so your lunch decisions are made after 1) already waiting in line 2) being faced with the pressure of ordering now and 3) not being able to politely back down if you all of a sudden realize "this place is WAY too expensive!". Therefore, from time to time, when one is just god-damn hungry your safest/only bet is to eat at the places you know and of course McDonald's is always just around the corner.

Therefore I now see the connection between stupidity/ignorance and obesity. Thank you McDonald's for your worldwide consistency.
