I don't think I have any actual phobias considering I can be talked into doing most things. The closest to phobias would have to be heights. I never had this trouble until a few years ago, since I've been in the Sears Tower and Gateway Arch in my life and went in a plane less than a year ago (I'm apparently cool with planes, but not on top of structures). Was also deathly afraid of roller coasters ever since my first ride on a kiddie coaster with my cousin when I was like 3. Haven't allowed the opportunity to enter a coaster since I was 12 or 13 though so I don't know how I'd do now.
