I had a fun conversation with Dr. Rick Lehman about three medical-related issues in the news this week:

  • Usain Bolt losing an Olympic gold medal because another member of his relay team tested positive for a banned substance;
  • Apples that are genetically modified to not brown when they’re cut open and exposed to air;
  • Fit Bit-like devices that can predict when you’re getting sick.

Listen to our conversation here.
