Old and young consists of two possibilities. Older women and younger guys, or older guys and younger gals. Either way, it's a generational difference, meaning one will have wrinkly crap skin and most likely not too attractive hair if they still have any actually... Or being super soft and flexible and young and completely bursting with energy. When these two dimensions collide, always good things happen.
