Younger women care more about health than older women ... The younger you are, the more likely you are to be informed about your health -- if you're a woman, at least. That's the finding of a new survey that shows that Millennial women are generally more knowledgeable about their personal health than Boomers -- especially when it comes to immune health. 75% of Millennials said they feel well-informed about how to stay healthy, compared to just 39% of boomers. The disparity is the same when it comes to the health of their lady parts, with 63% of Millennials saying they're conscious of it, compared to just 29% of boomers.
