It's all in a name

Is it possible that your name predisposes you to a certain personality? Does your name actually drive you to a certain profession? Lately David and I have come across some people who seemed destined to live by the light of their last name. Check these out:

John Hill - a site grader
Dave Diggins - underground utilities
Captain Frank Comfort - Fire Safety

I guess with a name like Freeland, David is lucky he's not working for immigration.
