Yogurt-eating mice grow big ones and have 'swagger'

Mice that eat more yogurt are sexy and they know it. In an MIT study examining how probiotics affect weight gain, scientists fed one set of mice a normal diet and another set the same diet supplemented by vanilla yogurt. The latter group grew luscious, shiny coats and handled themselves like bosses. "You know when someone's at the top of their game, how they carry themselves differently? Well, imagine that in a mouse," said researcher Susan Erdman. Done and done. The report also showed that yogurt-eating mice grew huge balls and had "swagger." Greatest story ever? Greatest story ever.
