75. Sacrifice.

One of the things that sets us apart from the other creatures that share our planet is that we indulge in commerce. Trade.

Trade must have been around for a very long time indeed, from the first moment a person realised that he had too much of one thing and not enough of another. It just makes sense. And it must have made much more sense once we started farming, and manufacturing things like weapons or jewellery.

There’s always a good market for jewellery.

Another thing that sets us apart is religion. We have gods. We’ve always had gods.
