Identity and the mind response

The Darwin College Podcast by Raymond Tallis was really helpful and enlightening to a way in which a person should handle thinking about identity.  The idea that we are more like our neighbor of the same age than our two-year-old self, even though we consider our two-year-old self to be the same person as we are now was incredibly interesting.  The idea of personal identity over an extended period of time wherein we expect and see ourselves as ourselves, fix in that identity, and never changing is really interesting and strangely surreal.  I say surreal because at times I see myself acting in a way that I may have acted as a child or reminding myself to act like an adult.  In these ways, the verb "act" implies that I have not changed at all since my childhood self, only that I have a larger repertoire.
The part about identity and group identity where Tallis is speaking about the audience having the identity of an audience spiked my interest.  The idea of group identity, and at any given time, a group identity coalescing into personal identity is strange when identity is identity and not changing.  A = A as Tallis states.  For example, a chef becomes part of the group of the chef, and that possible transforms the way in which that person viewers their identity.
I also really enjoyed the segment about "I" as an allusion and truly nonexistent, only a construct of language.  This part bled into some of the ideas discussed in "metaphors we live by" and I began to think of "I or me" as a metaphor so deeply ingrained and apart of consciousness that it is impossible to think of oneself as being only part of a whole and not a singular entity. 
Overall, Tallis is incredibly intelligent and this podcast was a pleasure to listen to.  I don't feel like I can expand or repute any of the discussion.
