The menace of being experienced & aged is that the people to whom one can communicate with, are bidding their farewell silently from the stage ---- leaving you behind. Those who can understand you are slowly thinning out. You stand all alone.
Its a "Tragedy", reminding you an old number of Bee Gees.
The idea of a journey of all alone condenses, "Ekla Chalo" i.e. the life journey of a single individual .... to unknown destinations .... to the land of "Lote Eaters" or ... some other dimensions of existential plane.
