3 types

in the genetic realm,

there are 3 kinds of people:

X: eats every meal like it's his/her last, and yet stays a david beckham/jennifer garner.

Y: amount of food intake correlates positively to weight. so when B eats less, B weighs less.

Z: weight gain just happens, no food is required.

ladies & gentlemen, it doesn't take a genius to understand that i belong to the Z family.
