According to a survey at StudyFinds.org the average adult only feels "perfectly healthy" 12 days a month.

Whether it's being sore from a work out, or my two giant dogs rough housing with me, or perhaps a caffeine headache, I typically can find some kind of ailment to complain about, and I'm not alone. If you experience a stiff back, sore knees, aching feet, or numerous other complaints, you're one of us too! Click the link in the tweet below to read more.
