David Ewing Duncan has spent the last 25 years being poked and prodded in the name of science. He’s signed up for hundreds of tests because, as a journalist, he writes about emerging health breakthroughs. He says one recent test contains more useful data than anything he’s seen to date. He talks to host Emily Kwong about his score on the Immune Health Metric, which was developed by immunologist John Tsang. Together, David and John explain why immune health is so central to overall health and how a simple blood test could one day predict disease before it starts.
