It has been reported that a study, jointly undertaken by Case Western and the National Institute of Health, has theorized that older people (e.g. yours truly) do worse on certain written tests because of their eye sight not because of mental deterioration.
When younger test takers were given tests with the font blurred to simulate declining eye sight, the younger test takers' scores were more in line with those of older test takers. This suggested that eye sight rather than cognitive ability may contribute more to this than previously thought.
This news was welcomed by really old people, who as parents had told my generation that all that self pleasuring would make you go blind and crazy and grow hair in the palm of your hand. Now they say, "We were almost right all along, it just made you blind and stupid."
Oh, well, thank goodness for Lasik surgery, cheap reading glasses and Nair.
