Fish

I'm a person who admittedly has a slight fear of fish biting at my feet and hurting me. The thought of fish harming me disgusts me for whatever reason, and it's the biggest problem I have with swimming in lakes and rivers. I can put away the fear normally and force myself to swim, but it does occasionally pop up once I'm in the water.

Interestingly enough, a salon now offers a treatment involving exactly what I fear. A person immerses their feet in a tub of water in which fish swim about and nibble. The fish then go about eating off dead skin, creating something of a bio-pedicure. Pretty interesting I suppose, and bizarre enough to be newsworthy.
