re: What’s your most irrational fear?

Getting trapped in a enclosed area like a pipe, a cave, even a window seat on an airplane can do it.

ETA: I've got another one.

Going over a crickety old low wooden bridge over water at night. Always felt like it was going to fall into the water or a wave would come over the bridge. But, it's only at night.

I may need a team of psychiatrists to check me out.
