The higher-T among us seem significantly brain damaged since high school (myself included). I wonder what the mechanism would be here...
Any sensible statistical analysis of brain damage must control for common brain injury factors, chief among them American football and frequenting Less Wrong. My money is on rat poison and not T poison.
Yet another dude who watched Wolf of Wall Street and thought "yes, this is what peek success looks like, I'll aspire to be like this". Absolute rubes the lot of them.
