In addition to a touching personal tribute, this article also illustrates the jobs crisis for PhD graduates. Someone who started his career in the 1950s works into his eighties, teaching from hospital, and dies less than a week after retiring. This is not a good model, and a good argument for mandatory retirement ages.

Define 'bad'. You're an emotivist by the way.
