Emily's list: Pittsburgh Steeler Troy Polamalu's hair insurance edition

I know there are many types of insurance. Each month, I pay car insurance, health insurance and renters insurance, and I just got an insurance policy to cover my engagement ring. I'm familiar with homeowners insurance, pet health insurance and even identity theft insurance. But hair insurance? Voice insurance? Taste bud insurance? These policies exist, and famous figures and their endorsers actually spend big money on them.

Time says there have also been policies on David Beckham's whole body, Dolly Parton's breasts, Bruce Springsteen's voice, the crossed eyes of silent film comedian Ben Turpin, and the booty, knees and ankles of a Brazilian Playmate. I have to wonder whether this was actually money well spent. Some of us can't afford health insurance, while Australian cricket player Merv Hughes had his famous mustache insured for a cool $370,000.

I know, I know, they're publicity stunts, and I'm falling for one now. (Photo above is courtesy of Head & Shoulders. There, I've mentioned the product again.) But looking at it strictly as a financial arrangement, I have to wonder if it is it really worth it for these companies paying to insure body parts. After all, nothing lasts forever. Voices change, body parts begin to age and droop. What if Polamalu goes bald?
