I think you're cute, but I think you'd look a lot better smiling :) Trust me, I don't think I've ever seen a person smile and looked bad. Smiles do wonders for a face and can make a 4 look like an 8. Plus, people are attracted and like to be around happy people.
I mean, your ancestors had to fight fucking bears and big ass saber tooth tigers WITH A STICK in order to survive, as well as to have something to eat. They had to learn how to make fire to keep warm, how to craft shelter to deal with the elements.
Basically, the odds were stacked well against them. But do you know what? They survived and prospered. So you might want to at least smile like you're happy to be alive.
