Beth, I may be stating the obvious, but it's not your brother's fault he's a genius...but it's also not clear to me that the "Dr. Spock" nickname was a compliment either...there are often "social trade-offs" that come with extreme intelligence...but enough about him.
As to you: WOW! A biologist in the Mississippi Delta, an area that has been environmentally devastated following Katrina. I know that you can be anywhere you want to be...but it seems to me that you've chosen that place for a reason...even if it is the most humid place in the world
As a guy who got a "c" in biology in high school and avoided it in college, I'm glad that we have people like you who enjoy and are committed to working on the things you do as well.
