Well I go back to anesthesia, that allows you to do both better diagnosis, and better treatment. So you know, I sound like a broken record, I know, but our diagnostic modalities have improved with the digital x-ray, with laparoscopy, with better analysis of blood and tissue, and things like that, and treatment is improved too because we know, like we talked about on how antibiotics, what doses of antibiotics, how often we should give them, we’ve got better vaccines now for protecting infectious diseases. But it still doesn’t go away from the fact that, you know, without anesthesia, we wouldn’t have as many improvements as we’ve seen.
