Up with life!

So the Jsun and I were at a Wilderness First Aid class, and we realized something important: Someday a hard-on just might save your life. We were discussing heart attacks and vasodilators (incidentally, vasodilation is one of my favorite words...and phenomena...) and Jsun made the point that, because it is a vasodilator, if you were having a heart attack Viagra might just save your life. Boners for survival, that's Science!
