I went to the client subsidised canteen for lunch with my team today. I selected some nice salad from the buffet, and decided to weigh it before heading for the till. At today's conversion rates it was 12 bucks for green leaves and Greek salad.

I put it down and had a very nice pie and chips for half that.

We have a situation where a significant portion of our society is having to make choices at the margin that it is evolutionarily unable to do.

I think we have many challenges ahead of us before we reach that golden future of humanity. wars, climate change, to name two, but they come down to the same problem we have with obesity - arranging our society to ensure our inner chimp's less helpful evolutionary urges do the least damage.
