My biggest fear in life is heights. Too scary to be up so high.
The formal term is called acrophobia, and I have it a lot too. I really hate heights
Yeah, my ex had me go on a roller coaster that was like the tallest in the park, I was so scared. 
I would say so! I can relate. When I am up on high bridges I feel so awful. Some people even have panic attacks in high places and cant get down themselves!
I don't mind bridges, usually. I guess I feel safe in the car, but I can't really get up on a ladder either
Can you imagine not having a fear for heights, those who do have what they call a head for heights
That is interesting, never heard of that before. Must be a good feeling for them.
It really helps for hiking and climbing! haha.
