Last week, while out for a run, I felt a sharp pain in my knee. Inspection revealed no obvious biomechanical issue, and the pain was intermittent. Still I took it easy until I returned home. While the area where I had felt the pain was swollen, it was not discolored. Discolored areas generally indicate the …
Is the Disconnect between Biology and Culture making you Ill? Part Three: Homeostasis and Couch Potatoes who were Born to Run.
Homeostasis is really about balance, and in this case, energy balance. We are predisposed to maintain this homeostasis by taking advantage of surplus energy and storing it as fat. And while this trait has served our species for 2 million years, we no longer live in a feast or famine environment, and those conditions of …
Is the Disconnect between Biology and Culture making you Ill? Part Two: Stressing the system
The human immune response system, much like that of other mammals, evolved over hundreds of thousands of years to be a barrier against the nasty bugs and pathogens we live with day-to-day. Since the discovery of antibiotics (and their overuse in both human medicine and industrial farming), we have created a very clean and sterile …
Is the Disconnect between Biology and Culture making you Ill? Part One: Evolutionary Medicine.
Part One: Background Over the winter, rather disgusted at the weight that I put on over the past 20 years, I decided to do something about it. Complaining was easy, but taking steps to improve my health also proved to be quite easy as well. About 25 years ago, I was diagnosed with metabolic syndrome, …

Climate Disruption, Forest Fragmentation: How Reduced Biodiversity leads to Increased Disease Load from Zoonosis.
Recently, an exchange on social media concerning Lyme disease and ticks prompted a good deal of disinformation, which was followed by several text messages to me asking such questions as, "Can ticks really carry rabies?" or, "Is there a vaccine for Lyme disease?" At a time of climactic change, we are seeing a rapid rise in …
How the Evolutionary Left-overs of Intuition, Bias, and Instinct, Hinder us in the Technological Age.
The philosopher William James believes that there were two different parts of thinking; that he labeled these two parts associative thinking, and true reasoning. According to this dual process theory, associative thinking was based in large part on past experiences from which we drew comparisons or abstractions. While true reasoning was reserved for tasks like …
