Moths.
When I was a kid, maybe 6 or 7, I had a really bad diabetic hypo attack one night in bed. Cold sweats. Fits. The works. I was soaked in sweat and shivering.
My mum took me downstairs and opened up the under stairs chubby hole to get me a blanket. Soon as that blanket was lifted, the biggest moth I'd ever seen flew out and zoomed past my head within inches. This thing was so big it had brass knuckle dusters on. Scared the life out of me.
I've been terrified of them ever since.
Getting lost.
The main reason I bought my etrex20 4 years ago was the fear of losing sight of the bike club in an unknown to me part of the country. The fear of being lost would have sent me into a panic which would then cause a diabetic hypo. That would then lead to me losing control of the bike and under the wheels of a Cheshire mum's BMW X4. As cruel a way to die as there is.
Heights.
I didn't realize just how bad this was till recently on a camping trip with my fiancee. We climbed to the top of the highest tower in Conwy Castle and I cannot describe how scared I was looking over the edge. Pam was killing herself laughing at my face as she's never seen me so petrified. She had to hold my hand coming back down that bloody joke of a staircase. Never again.
