I have two fears. One is having a heart attack. Now than I am older (63) every time I feel any type of a sensation in my chest or arms, I think I'm having one. I don't go to the Doctor or anything but I do think about it. I am not overweigt, all my vitals are fine but I start to worry.
The other is fear of flying. Well not really flying, but crashing. I wish the Pilot would make a lot of announcement so that way I will know everything is OK. I always keep my eye on the Stewardess to see what they are up to. That relaxes me. I also pray and bless myself on take off and landings.
