Hello, I'm new to the site. I found you in comments on The Perfect Health Diet site (authors, Jaminet). I'm 52 and have been declining in health for the past 10 years. Once very fit and active, cycling and bootcamp almost daily, I started struggled with muscle pain, joint pain, and fatigue around 2007. I'm suspecting either Lyme or C. pneumonia infection. Symptoms initially seemed like classic Hypothyroid, though TSH was always in range, so my old doc would not treat me.
Things that happened around 2007: I divorced, moved to a home with a garden that came with a lot of yard work, and bought a summer cottage in Long Island near the Ferry to Connecticut, where I also did a lot of yard work.
