Several years ago I fell off the top of a 30' ladder. I was painting the trim on a third story window and the bottom of the ladder kicked out a bit, the ladder dropped a couple feet and stopped suddenly and I hit a rung like it was a diving board. I wasn't injured physically, in fact I held on to the paint brush and bucket all the way down and didn't spill a drop (let's talk about angels some time). My body was fine, but ever since that day I've had an issue with heights.
Once or twice a year I force myself to go off the high dive at the pool so my kids don't think I'm a big chicken.
I used to love roller coasters. Not any more.
So, it shouldn't surprise me that I get a bit of a queasy feeling when I ride the pedestrian bridge that spans I-435 at Roe every morning.
