fairly obscure majors?! help

<p>hi everyone!
so Im applying to USC right now and the major I put on my app is sociology.
however, im also really interested in attending the davis school of gerontology, as a gerontology major.
can someone tell me a little bit about both those majors and how they're related in any way? I cant seem to decide...</p>

<p>oh and its okay even if youre not strictly speaking of USC, I just need an idea of what these majors are going to be like.</p>
