Caught one part of Lord Winston's The Human Body last night in which he aired someone else's numbnuts theory: that humans have uniquely long lifespans amonsgt mammals because we have adapted to become good grandparents.
What percentage of human beings throughout history (and particularly the early part when we were still evolving at pace) does he reckon managed to live beyond 50? And indeed, how many people alive in the world today will get past middle-age?
The programme also related how Claude Monet had a cataract removed before proceeding to paint a number of scenes with one or other of his eyes shut. When the clouded lens was used, the colour red predominated. Monet got so angry about this bias that he even resorted to destroying some works created before his operation.
