This week Zi and Vindesh explore how traumatic events shape our physiology.  Stress is unavoidable, but we can manage it to improve our health rather then age us.  Zi discusses studies that show the presence of a loved one or a community helps offset bad stress.  One of the major predictors of good health is the presence of oxytocin.  A hug, snuggle, or an intimate meal  with a loved one is enough to take your physical body from distress to "eustress," the good stress.  Since we know this now, why aren't we practicing more compassion as a society? Zi shares his insight on why chemical reactions affect our behavior.
