Defining Old and Older

Speaking for myself, the definition of being old and getting older or being older are totally different.  I often wonder when old age starts.  Some of my observations in life have unanswered questions pertaining to these statements or questions.  So I am asking you the listening audience to join in the discussion and share your comments.  Help us out with the terms Old and Older.  This should be interesting to say the least.  Peace!
