This is coming from the question on [active versus passive stretching](https://fitness.stackexchange.com/questions/44860/active-flexibility-to-static-passive-flexibility-good-ratio).

From the help section on off topic -

* the rules of a sport
* a purchase recommendation
* nutrition unrelated to exercise, such as food safety, nutritional needs for children, etc.
* **wellness, general health**, medical advice and injuries **unrelated to exercise**

I believe it to fit into the last category, because there is no fitness program, goal or related question stated in the post. It is academic and interesting, but I am not sure it fits, and could open the door for other similar questions about general health, which have been pretty much universally off topic since shortly after the site launched 11 years ago.

For reference, some of the historical meta discussions on general health and similar:
