For years and years, I was a serious nail biter. My mother tried everything she could think of to get me to break the habit: hot sauce, soap, perfume, lemon juice. Nothing worked. I wasn't an especially nervous kid, but I was a serious thinker and would bite my nails and twirl my hair when lost in my thoughts or a book.
It wasn't until I got braces as an adult that I stopped biting my nails. And the only reason I stopped biting them then was because I couldn't figure out a way to get around the metal in my mouth to latch onto the nail to bite into it! Once I stopped biting them, my fingernails grew in nice and strong, just like my mom's used to.
This photo was snapped with my iPhone while I was stopped at a red light and my left hand was draped over the steering wheel. Yes, folks, these nails belong to me! They are not bought and paid for -- they are au natural!
