Too few of us are doing this at all, let alone routinely. Everyone i know who examines themselves carefully from head to toe has previously had a major health concern. Do you look yourself over and do your own basic checks, like breast exam and testicular exam? If so, what motivated the behavior for you? And if not, why not?
How often do you give yourself the full once over?
I only go for check ups once every few years or so, cause I think most of the issues I encounter are something I can resolve without a professional. I have one minor issue that I go for routine check ups with, but it's not too invasive.
