Raymond Tallis, the fellow portrayed here, has an article in the current issue of The New Atlantis about time.
I won't discuss his views on this topic, but I will offer something of a tease. He begins with a passage on his own sense of mortality that I found moving.
"On each January 1 the number designating the year just past looks less used up than its predecessor. By the time 1960 had arrived, my 1959 was worn out and its replacement overdue. When 2011 was announced, I was still not used to 2010 and even 2009 and 2008 looked scarcely touched. It is hardly surprising that I sometimes feel — as I imagine you, reader, do when yet another day, another week, another summer, another year has melted away — as if I were being swept, log-like, towards a cataract dropping into oblivion."
