We've always known dancers are special. (Duh.) But here's a fun Friday factoid: Did you know that there are actually genetic differences that separate dancers from non-dancers?
Seriously! A study suggests that dancers "show consistent differences in two key genes from the general population." Those particular genes are involved in the way information is transmitted from nerve cell to nerve cell. After that the report gets pretty intense and science-y, but the gist of it is that our dancer-ness is, in a way, actually embedded in our genetic code.
