Yes.
Let me tell you when, why, and how I learned that you need to pay attention to taxes.
I was in third grade and my class had a field trip. This was 47 years ago, so the exact details of the trip are lost to time and rusty memory. The lesson remained.
There was something that the class could purchase at the end of the day on the trip and the place only took cash and the school was not doing anything to help, except tell the kids about it and the price. Which was something like $5. I told my Mom and she handed me a $5 bill, plus a quarter, which confused my 3rd grade brain. She said to due to some strange words "sales tax, which was 5% in my state at the time. Got to school that morning and all my classmates were proud that they had their $5 bill, but none seemed to have a quarter. So I kept the presence of my quarter a secret and was a little embarrassed about it. Yes, I was young and stupid. Now I am old and stupid.
When it came time to purchase the whatsit at the end of the day, me and one other of my classmates produced a quarter to buy it. The teachers and chaperones had to cover the sales tax for the other 20 kids and they were pissed.
I went to school and learned a lesson that has stuck with me for nearly 50 years.
Because it is a LOT more complicated than that.
Not all rheumatological diseases are due to the immune system’s memory. As a case in point, Ankylosing Spondylitis is theorized as being caused by a mis-folded HLA-B27 protein response. The mis-folded protein response is caused by cellular stress, at least that is the theory. The lead singer of Imagine Dragon Dan Reynolds suffers from this disease. So there are people out there suffering from it, it’s not just some disease out in left field no one has heard of before.
Are there diseases that could be treated by clearing the immune system’s memory? Possibly, but there would also be consequences for that as well. Mainly, because the actual method by which the memory works is not completely understood.
