The Lost Year of Telife

Stephen Ocaso: I once made foray into trying to do natural experiments in medicine, and i got burned so badly that i've never gone back. When a patient shows up at the emergency room, he or she has no idea what doctors are going to be working at that time. And if some doctors are better than others, then as a patient, i can get lucky or unlucky depending on which doctors are working. This let set up makes sens absolutely ok.
