So after reading chapter 2.3 I found my first related topic. Arthritis pain and weather. After 10 years active duty military I received 3 surgeries on my ankle. Immediately after I developed post traumatic arthritis which I am to live with for the rest of my life. Now I don’t claim to be able to predict weather or even tell when it’s going to rain; however, I will tell you this when it does rain I have like 50% more stiffness and pain than when it’s not raining. So the book states that I’m experiencing an illusory correlation but I can assert that my increased pain is no such illusion. Sometimes when it rains I can even walk, whereas that never happens when it’s not.
