It's no surprise that a lot of doctors develop a God complex. They're healers, they know a lot, and they usually help you feel better. And their patients usually throw praise and hosannas their way.
Practicing medicine involves a big dose of glory. But hey, if someone waves a magic medical wand that takes the pain away, wouldn't that be a glorious thing? You may find yourself on holiday card lists, or being invited to weddings, christenings, bar/bat mitzvahs, or having your name among the grateful acknowledgments of a best-selling book written by one of your patients.
