Identity Change

Just changed my identity card. Surprises me when I juxtapose the old and new cards and compare the photos. I have changed considerably. I did not just change my identity card; I changed my physical and mental identity, and it happens moment to moment. But some things change more subtly, probably inconceivably in this life time - my thumbprint and blood group printed on the cards. Funny that that's almost all that the country uses at the moment to recognise me as me. Our individual identity is so fragile. But I like it this way - the possibilities of infinite change is most welcomed. How else we we evolve to be better?
