Here's another quick "how lazy are we" update: Someone on Twitter asked the question, "Do you wash your legs when you take a shower?" And after close to a million votes, the results are in... 1 in 5 people DON'T wash their legs.

80% said they do, 20% said they don't, and people on both sides have strong feelings about it. So you do really need to wash them? Or does the run-off from washing the top half of your body do enough?

tackled this a few years ago after a character on the sitcom "You're the Worst" said she didn't wash her legs. Here's his answer: "Unless your legs are visibly soiled, you don't actually need to wash them." He says the soap running down your body removes most of the dirt and sweat on its own.
