When i was in my mid 20s, living in inner London was vital to me, because it meant i was close to the cool bars, nightclubs, art galleries (really!), and all my friends, who also lived in inner London. Now i am approaching my 40s, none of those things are much use to me, but i appreciate the fact that in my not-quite-inner-London suburb i have a good neighbourhood coffee shop, and some excellent bakeries and a big DIY shop nearby. I should imagine that in my 60s, i will value different things, and in my 80s, different things again.
