The boner measurement may seem weird, but it’s a very informative measure of general health, vascular health, and a few other things.

My friend who worked in a sleep lab as a student was tasked with measuring several aspects of boners. The Netflix movie “game changers” (or “you are what you eat”, don’t remember) also used these measurements to drive a point.

It is not any weirder than a urine test or fecal analysis, which we all take for granted when looking for specific markers (e.g. protein in urine or occult blood in feces). It is, however, much cheaper and easier to carry out in a daily basis.
