“ it is all clearer now than it was then. Rhea would say it is the vivid fabrications of an ageing mind. More likely, though, it is the clarity that comes from ageing - from the natural process of releasing the mind from imagined futures, and allow the present and paste to take their rightful place at the centre of our attention. The past is palpable to Sheldon now, in the way the future is to the young. It is either a brief curse or a gift before oblivion. ”
