truth in advertising

I heard a TV ad this morning for a medical office that speciaizes in surgery for skin cancer. Their ad said that coming to them for your surgery needs would give you "life changing results."  At first I thought that sounded good, but the more I considered it, the more I realized that it is very non-commital.  Does 'life changing' mean that I'll look like I had an amazing face lift?  If so, sign me up.  Or does 'life changing' mean that I'll die under the knife?  Either option would be life changing.  The more I think about it, the more I think that their attorney recommended this slogan.  Please note, I am not criticizing attorneys.  Merely commenting on a pretty law-suit-proof slogan.
