Writer and editor for the Washington Post is here in Oxford for the Tomorrow's People meeting. I caught up with Joel in the Blackwell's book show as he was looking at a copy of my book, Genetically Modified Athletes. He mentions some of the issues in his own new publication 'Radical Evolution: the Promise and Peril of Enhancing Our Minds, Our Bodies - and What it Means to be Human. One of the bigger questions we discussed was how wide an issue the sport one really represents, on the one hand a specific problem for sports organisers, but also a high political problem for various governments.
