fear of heights

I saw something on TV about some blind dude being the first blind person to climb Mt Everest and it got me thinknig,do blind people have a fear of heights?:confused:

Well, they certainly can have a fear of falling. So if their senses tell them they are at risk for that when on the edge of something, and that makes them for than normally apprehensive, then yes, I suppose we can call that a fear of heights.

True but I was wondering how they could have a fear like mine not really a fear but the higher I climb (I used to work in a refinery and would climb tall towers 290 feet high) the harder I would have to hold on and wen I got really high up I could not let go with one hand until I had a good firm grip with the other.
