The year—and the decade—is drawing to a close, and we’ve had another physiology-ful year on the I Spy Physiology blog. In 2019, we’ve explored how horses power themselves and how groundhogs survive the long winter, and we have highlighted the important breakthrough of a new treatment for cystic fibrosis. We’ve also continued to flesh out our “Spotlight” series, which explains fundamental physiology concepts to our readers. This week, we highlight your favorite posts of the year in our top 10 most-read list.

Diet and exercise topics continue to trend on social media, as well as on I Spy. The genetics behind finding a life partner was popular, too. Cutting-edge studies presented at the Experimental Biology meeting, how filmmakers get physiology wrong in horror movies and a look at cannabidiol’s (CBD’s) effect on the vascular system rounded out the list. Here are the top 10:

1. Why Being an ‘Active Couch Potato’ Is Bad for Your Health
2. 23 and We? Mating for Life Could Be Genetic
3. Ketogenic Diets: Passing Fad or Nutritional Hack?
4. Type 2 Diabetes and You: It’s Complicated
5. A ‘Holy Grail’ for Exercise Recovery?
6. Can Intermittent Fasting Help People with Diabetes?
7. The Iceman: Wim Hof Is a Real-life Superhero
8. Connections between Food, Drink and the Brain: Research from Experimental Biology 2019
9. Horror-ibly Wrong Physiology in Scary Movies
10. The CBD Craze: How It Affects the Vascular System
