Is there any correlation between testosterone and interest in math and science? I loved math and science when I was younger. I got a 3.90 GPA with a double major in ME and math. But lately my interest has completely vanished. I'm considering the possibility that it doesn't interest me anymore because my T levels have skyrocketed. I started lifting heavy and got a wife. I just recently dropped out of my PhD program to take a $60k engineering job (a lot for my area of living) and my goal is to just drop out of society and ranch cattle with my wife once I save enough. I've also noticed that most people who lift have very little interest in science, and people who have interest in science usually aren't interested in lifting.
