@BillW,
13 Frightening things
1. Looking downward when you're on a high place.
2. Hearing a noise downstairs at night, then having to be brave to investigate.
3. The night. A paralyzing fear that consumed me for 50 years. I recovered, and now I love it.
4. If Earth's sun went Supernova - well, only for a few minutes..
5. Tangled airline when full-suit diving Shocked
6. Getting stuck, flashlight stop working, lost when spelunking alone.
7. Car stalling while on a country lane. (The days of no mobile phones)
