I got it through heredity, not this bad dentistry stuff I hear. It's cool and my hands and feet turn a color I can only describe as peanut butter & jelly.
Anywho, does one count volunteer work on their taxes? If so, is it actually volunteer work? If you hurt yourself when volunteering, well, it's gonna be on you. Dunno what I can say besides life insurance or something.
