The Fall Olympics #Sochi2014

Remember the Fall Olympics in Vancouver? That was the year that skaters … not the racing ones but the dancing ones … were falling all the time as if they had some kind of special extra slippery ice on the skating rink. Well, this year, at Sochi II, we are witnessing the Fall Olympics mainly…

Manspace

In an old colonial-looking restaurant that served ten kinds of steaks, I met up with an experienced explorer and a local farmer, to have dinner and discuss plans for an upcoming research project that would be managed by The Explorer and that would partly be on The Farmer’s land, which adjoined a rather extensive and…

Why Do Men Hunt and Women Shop?

The title of this post is, of course, a parody of the sociobiological, or in modern parlance, the “evolutionary psychology” argument linking behaviors that evolved in our species during the long slog known as The Pleistocene with today’s behavior in the modern predator-free food-rich world.
