Advice

I'm in the mood for a grand gesture. Should I shave my head to raise funds for pediatric cancer research? Would I be silly, grandiose, vain, or something else to go ahead with it? Would I be chicken-sh-t not to do it now that I've thought of it? What would I look like without hair?
At least I know my hair grows fast. I'd only be a grotesque fashion statement for a couple of weeks. Then I'd be fashionably punk.
