The Power Of Genetics
You know the kind of thing: it is Sunday morning and you have nothing better to do, so you start the photographic equivalent of doodling. You find a photograph of your father taken when he was about 72, which, by chance, is your age right now. You take a selfie and merge the two images to see what you will get and you are suddenly reminded of the power of genetics. The past and the present stare back at you.
Note to my son: in forty-odd years time feel free to merge your portrait into the composite. Note to my grandson: in seventy years time .... etc etc.
