Acrophbia is my biggest fear!

Acrophobia? Is that like a fear of heights or something?
0_Apprentice
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!
1_Wizard
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?
1_Wizard
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
