It’s true. Belly buttons don’t get nearly enough love. (cc-by lemasney)
“The navel (clinically known as the umbilicus, colloquially known as the belly button, or tummy button) is a scar[1] on the abdomen at the attachment site of the umbilical cord. All placental mammals have a navel, and it is quite conspicuous in humans.[2] Other animals’ navels tend to be smoother and flatter, often nothing more than a thin line, and are often obscured by fur.[3]” – Navel – Wikipedia, the free encyclopedia, https://goo.gl/8GvGtv
