I am an ectomorphic introvert who skipped two grades early on in my academic career. I was (and maybe still am) the dream of bullies everywhere.
Middle-aging has forced me to relinquish my obsession (which had me turning to increasingly dangerous protocols to stave off the deleteriuos effects of aging on my ability to build and maintain muscle mass). I have freed up a lot of mental energy and learning time. It's as if my true, wiser, brainier self emerged from the husk of the bulked-up emotional monster I had become.
