I'm really dumb, just believe me on that one. My parents are like this too. How did my ancestors survive with brains like this? How are our genes still propagating? There's no trait like height or attractiveness we have either. Our family is full of highschool dropout alcholics, felons, chronic stoners, criminals, just the dumpster fire of humanity. How did my family's ancestors survive with these shitty brains and bodies? Why?
