I think I tend to stay away from anything that evokes fear in me, or, if I can, eliminate it altogether.
Because of an incident I've experienced when I was little, I for the life of me can't swim. Because of that, imagining that I have to wade or otherwise go through a deep body of water where I can't see the bottom is enough to send shivers down my spine. If I had to play at the beach, I would stay at the shallows and not venture too far; the farthest I would go is probably up to waist-high, lower if the water is murky. Similarly, if I were to ride a boat or ship, I would stay away from the sides at all times.
And I've got this rather weird fear of snails and slugs, or limbless slimy animals in general. If I came across some on the streets, I would circle around it and continue on my merry way. However, if I found one in the house, then I would grab a handful of salt and use it to kill the pest. If there's no salt, anything goes: sugar, soy sauce, detergent powder, hot water, just about anything that I can get my hands on. I wouldn't even think of relocating it outside, and the mess I would just leave to someone else to clear.
