Thank you.
I want to go back to continue on some of the previous questions. Mr. Easter touched on them--the retiring of a number of the staff, and what have you. What kind of program is in place as far as researchers are concerned? There must be some kind of program in there where you're bringing in new young people with new thoughts. What's the ratio of young researchers who come into the department on a yearly basis as far as a percentage number goes? Are there any numbers on that?
