Is Northern English 'Older' than Southern English?

About

I make videos mainly about topics in linguistics, but occasionally about anthropology in general. Me and a few friends produce comedy films and sketches, some of which will probably be published soon. I had previously used my university email address here, but I am using a personal one for the time being - it should be attached somewhere on the 'about' page. I don't have a lot of free time at the moment, so I won't be able to reply to everything :( However, I'll check emails regularly, and set aside time to respond every few days.
