I spent many years writing books on evidence-based evaluation of alternative medicine, but only now, late in life, have I found what feels like my calling. These days, I write fairly difficult popular science books on biology-related topics for those who like to be intellectually challenged. My previous claim to fame was inventing the word "orthorexia nervosa."

I grew up as something of a child prodigy under the false belief that I was talented in mathematics. After graduating with a math degree, I returned to college to do pre-med and go to medical school (to make a living). It was then that began to notice that I loved biology; but I thought nothing of it. Now, retired, after raising a family, I seem to have at last found my way to doing what I love.
