This Is What Your Belly Button Says About You The Huffington Post | By David Freeman Talk about navel gazing! Scientists have been eyeing innies and ogling outies for years now, and some of their findings are pretty astonishing. So if you think your navel has nothing to do but sit there and collect lint, check out(ie) our list of eight surprising belly button facts. You'll be amazed at just how much your little umbilicus has to say about you. 1. You're a hottie. Some belly buttons are sexier than others. And that's been backed up by science. University of Helsinki researcher Aki Sinkkonen says we tend to like navels that are T-shaped or oval and vertical, with a little hooding, LiveScience reported in 2009. Outies? They get a thumbs down. So do innies that are too deep. What's more, Sinkkonen says a woman's navel actually signals her reproductive fitness. "I suggest that the symmetry, shape, and position of umbilicus can be used to estimate the reproductive potential of fertile females, including risks of certain genetically and maternally inherited fetal anomalies," he wrote in The FASEB Journal, according to LiveScience. 2. But you're no Karolina Kurkova. All placental mammals, including humans, have a belly button--because all of us were once attached to our mothers' bodies via an umbilical cord. Supermodel Karolina Kurkova reportedly doesn't have one, but only because it was removed during an operation she had in infancy. So if you have a navel down there, rest assured you can't be Karolina. Another celebrity rumored to have lost his belly button to surgery is Alfred Hitchcock. But it's not clear whether the rumors are true. More>
