Hey it's Mark!  Answering 100+ emails a day has become too much of a timesink for me, so I've closed down my contact form while I build my house and write my next book.

1) If you have a question related to a purchase, reply to your email receipt from us and I'll get back to you usually within 24-48 hours.  If you want one of our famous red lights, click here.

2) If you're not already, be sure to subscribe to our newsletter and I'll let you know when my next blockbuster book is ready.

3) And of course, read all my books if you haven't yet as each one builds upon the previous work and we're advancing our understanding of disease and health together.  Scroll down and order yourself some crisp paperbacks today...
