Retired high school biology teacher Frederick Earlstein lives to research. When his only niece was diagnosed with postural orthostatic tachycardia syndrome (POTS) at age 14, Earlstein felt helpless. His answer was to start researching the condition and sharing everything he learned with his sister and her family. That project not only resulted in a book on the subject, but also to the successful management of the girl’s condition.

Earlstein applied the same approach to his own minor problems with blood pressure, allergies, and degenerative disc disease. “It’s all about critical mass,” he says. “When the notes on my laptop and those piled up on my actual desktop reach a certain level, I start realizing there’s a book in there somewhere.”
Writing about medical issues in plain English has become Earlstein’s second career. After retiring from his career as an educator, he began looking around for something to occupy his time. “You can only clean out the garage so many times,” he said. “I was trained to be an academic and old habits die hard.”

Now Earlstein works daily in his home office on whatever manuscript he has at hand. He describes the work as the perfect combination of intellectual challenge and self-employment. “I decide what to write about and when to write it,” Earlstein says. “Typically I pick a subject because I know someone who is grappling with the problem and with understanding the information they’re being given.”
