Heights, that's a fairly recent development and one I am working to overcome. Stick me in a mountain tram and I am pretty entertaining.
Also, after a near car accident years ago, I really hate passing other cars. Makes me nuts. Erik doesn't sympathize with this fear.
And the worst, as my parents age, I obsess about being without them. I know it hurts everyone when you lose a parent, but I'm not sure I will be able to handle it. And I'm not typically a weenie.
