You can train your body into thinking it’s had medicine
Wim Hoff [1] is a great example of someone who can turn a lot of the knobs on his metabolism that aren't available to most of us.  Apparently, he says it's something you can learn to do.  If these researchers got more concrete about how patients can learn to do this and to get physiologically measurable effects, it would actually certainly lower health care costs.[1] https://en.wikipedia.org/wiki/Wim_Hof
