It is unthinkable to have a British countryside that doesn't have actual functioning farmers riding tractors, cows in fields, things like that.

So, if people didn’t settle down to take up farming, why then did they embark on this entirely new way of living? We have no idea – or actually, we have lots of ideas, but we don’t know if any of them are right. According to Felipe Fernández-Armesto, at least thirty-eight theories have been put forward to explain why people took to living in communities: that they were driven to it by climatic change, or by a wish to stay near their dead, or by a powerful desire to brew and drink beer, which could only be indulged by staying in one place.

There are only three things that can kill a farmer: lightning, rolling over in a tractor, and old age.

Take a moment from time to time to remember that you are alive. I know this sounds a trifle obvious, but it is amazing how little time we take to remark upon this singular and gratifying fact. By the most astounding stroke of luck an infinitesimal portion of all the matter in the universe came together to create you and for the tiniest moment in the great span of eternity you have the incomparable privilege to exist.

Physics is really nothing more than a search for ultimate simplicity, but so far all we have is a kind of elegant messiness.

If you can imagine a man having a vasectomy without anesthetic to the sound of frantic sitar-playing, you will have some idea of what popular Turkish music is like.
