When I saw those pictures of Jon Gosselin scaling big roofs, I thought to myself that I probably would not be able to do that job. I am afraid of heights and even though I try and overcome that by going to the tops of buildings and looking over the edge, I just can't do it. I remember one time being in Toronto in the CN Tower and they have some glass in the floor which looks straight down to the ground. All these kids were running back and forth across it and did not have a care in the world. Meanwhile, all the adults would creep really close to the edge and very few ventured out on the glass itself. So, my question to you is do you have a fear of heights and have you done anything to try and overcome it? You can also discuss any other phobias you have.
