To get a flavour of Sapolsky's amazing work, there are at least two audiobook lectures at iTunes U on the work from Zebras on stress. The first is Why Zebras Don't Get Ulcers; the second is Stress and Coping: What Baboons can Teach Us. These are both free, and part of Stanford's Healthy Living Series at iTunes U. The take aways from Baboons are perhaps no surprise, but that they are so well underlined with both observation and physiology is well worth exploring.Very definitely worth listening to.
mc's posts are always worth reading and reflecting on. (interview with her here)
