    Scientists Have Discovered Why Humans Don't Walk Sideways Like Crabs

    Finally, an answer to this very important question.

    Ever asked yourself why humans don't walk like crabs?

    This is the kind of sideways walking the scientists investigated.

    It turns out that walking sideways involves a lot of stopping and starting and ends up burning as many calories as running does.

    Which is great is you want to get fit but not so good if you just want to go about your daily life.

    The good news from this study is that our lack of sideways walking isn't because we're not good at it. It's just because it's not metabolically optimal.

    And also because it makes you look like an idiot.
