Commercials are about sex appeal. There's a reason diet drink ads feature people who don't look like they need to diet. The Kim Kardashian Shape Ups commercial during the Super Bowl was a riot. "Oh, no, we weren't selling thirty seconds of softcore! It was about shoes!" Riiiiiiiiiight.
There's a new sexually suggestive workout aid called the Free Flexor. (Sorry, LJ won't let me embed media here anymore, here's a clicky.) Folks, I defy you to try making it through the ad without laughing once. It is just so absurd.
Supposedly, we reach sexual maturity in our teens. Doesn't mean much when the mental maturity isn't part of the package.
