While I'm not exactly acrophobic, I don't really like heights much.
is that the extreme fear or phobia of heights?
That's the one! I can go upstairs, but put me high above the ground and I feel a little queasy. Are there many people like that, do you think?
yes many people including me have that phobia, its considered a space and motion discomfort, that share both similar causes and options for treatment
I'm sorry you also have this condition. What sort of treatments are available?
the easiest way is to not go up into high places! recent studies have cast doubt on a fear of falling or similar issues related to why they would be scared
That's good advice! And I do have a fear of either slipping and falling or being pushed, so the studies are wrong in my case.
studies show that there are about 2-5% of the general population that suffers from acrophobia 
That's a lot of people. Is it mainly females or are males susceptible to this phobia too?

I didn't feel like we had to put a photo on the cover, I wanted it to be more mysterious and more about Evanescence itself, not just me
