After a little verbal sparring with my wife and the nurse daughter, three butterfly bandages close the wound. I promised to go to the clinic if a red streak went from my knee to my brain or lock jaw set in, only kidding. I will probably get the shot today.
My point is simple; how many of us have wounds because of a wrong position? My knee will be fine in a couple of days, hearts don't heal so quickly. Be careful of the positions you take.
