Often on different ends of the spectrum with clustered interests. (Like, since I am allready in the grey area of stereotyping... : people that like sports often like cars, and branded clothing, people that like operas/classical music, rather read a good book, wether it is a science book or a literary work of art, than go to a wrestling match.
sports is an intersting thing in this. Cause more than other interest it is influenced by your upbringing.
I find it fascinating to see those things, how people differ and how they are alike, nature vs nurture etc.
