Michel,
Hi, I found it interesting you used to write for doctors. When I'm not copywriting, I'm a medical writer, and have written content and articles for medical magazines and medical web sites (that's where I started out, anyway
I've noticed that at times, I have to gently let my medical clients know, "It's okay to use words that don't have ten syllables in them..", especially if they are targeting lay people without a medical background. I believe that it's part of the fun and challenge: translating "medicalese" into "readable and understandable" while maintaining professionalism.

Best wishes,
Sheri
