Shit, son. According to Professor Timothy Salthouse (<---sick L-N, btw) of Virginia University, our brains starts malfunctioning by the tender age of 27. Our reasoning, speed of thought, and spatial visualisation all slowly start going to shits. For realz!??? Science doesn't lie. At least in one year I'll be 22--supposedly the peak of my brainy awesomeness. Bittersweet cause it's down hill from there. Gotta start soaking up the knowledge y'all!
