I don't think that is a fair interpretation of my words.So to clarify, what you are saying is that the perceptual aspect of the name and definition don't matter.
Well let's make sure it doesn't. If your doctor or local newspaper does that, then point firmly at the IOM report. Shove that science based authority in their face. If they dispute it, tell them to take it up with the IOM authors.The problem I have is that I'm afraid Exertion will be replaced with Exercise by the mainstream and doctors.
