Very interesting programme on BBC 2 Horizon, called The Nine Months That Made You (http://www.bbc.co.uk/programmes/b013c8kd). I really recommend watching it. The basic idea is that by looking at how our time in the womb, which is connected to our birth weight, can be a predictor for diseases and our long-term health. It’s quite a shift in thinking. I will write again soon to comment on it…I’ve only just watched it and I’m still digesting/reflecting.
