I have two known conditional phobias...heights and spiders.

Heights - only when I feel the situation is clearly a hazard. I have been in airplanes and helicopters and have not felt the slightest bit uneasy during these times. Now, put me on a wobbly ladder, and you might just witness me soiling my shorts.

Spiders - Most of the time, spiders do not bother me. But get one of those dark spiders crawling on me, and I might just freak out! Most any insect can crawl on me and not bother me, but dark spiders make me crawl - I think it' s due to the fact that most poisonous spiders are either dark brown or black (or red).

So...what are your phobias?
