Quote by William Osler
As it can be maintained that all the great advances have come from men under forty, so the history of the world shows that a very large proportion of the evils may be traced to the sexagenarians, nearly all the great mistakes politically and socially, all of the worst poems, most of the bad pictures, a majority of the bad novels and not a few of the bad sermons and speeches.
