I’ve been on the road for the last week or so, gradually making my way by tramp steamer to Australia. By coincidence, I was on ABC radio’s Background Briefing programme on Sunday, talking about gift and market exchange in the world of human organ and tissue procurement. There’s a podcast of the show available if you want to listen. The topic is easy to treat in a glib or sensationalistic way, but I thought Ian Walker (who wrote and presented the show) did a really good job with it. There’s a lot of good first-hand material from organ and tissue donors, recipients and bankers, alongside stuff from me, Virginia Postrel and others.
