Yeah mate, as coincidence, I've been reading Mark Manson's book Models (which I think is good btw) and he covers demographics. I have to admit I've largely ignored this aspect...that social interactions are contextual, like attracts like, etc. I'm making the effort of going out in London because there seems to be so many more possibilities than locally which is the easiest but not the best option for me. But I've just been like "right girls, I'm here now...let the attraction commence!". But demographics can make a huge difference I reckon to results.

I think single people and couples without children, who choose to live in London, tend to be there because there's a lot of choice of places to go out and they like going out. But I've not really put any effort in to researching where what's going on. I'll see what I can find out and will see you soon bud.
