Speaker: Bill Caradonna. In Part 1 Iris structures are examined for their ability to measure physical resiliency (defined as: the ability to work hard with little stress; lower illness frequency; quicker recuperative time; and greater longevity potential).  The physical resiliency subtypes are also described (a useful illustration of the iris is included in the proceedings notes for this lecture), as well as minor and miscellaneous structural signs. Continued in Part 2.
