Acrophbia is my biggest fear!
Acrophobia? Is that like a fear of heights or something?
Yeah man. It freaks me out so much. Although it's not the height that bothers me so much, it's the thought of falling!
Phew! I get the tingles just thinking about it. Isn't a fear of falling pretty common though?
I don't know. I think it's a rational fear and survival mechanism. I mean why would anyone be comfortable with being up high?
Well, I've heard there's a complete opposite of a fear of heights called a head for heights. Those people love being up high! 
Yes! I've seen some of those videos of people in Dubai and Tokyo free climbing up buildings with no rope. SO crazy 
Do you ever have panic attacks when you're up high?
