I think constantly improving and updating your understanding of physiology is critical.

Wherever you are, whatever you have read - there is more.

And definitely ones you haven't encountered before.

Must process new ideas, they matter.

No the regulators won't keep up, but the doctor should.

Textbooks, lectures, journal articles.

Maybe even an unrelated field that had a similar conundrum?

I think most biology majors should read cells, gels and the engines of life.
