3. Pierced Navel
Among the interesting navel facts is a fact that only those with pierced navels will be aware of. While a pierced ear, nose or eyebrow heals in about 6 weeks, pierced navel can take anywhere between 9-12 months to heal completely!

While it is nothing to be shocked about, the reason behind this is the hairy stomach. Lint gets collected by the hair surrounding the navel and men, by default, have more hair than women.
