> And just this past July, Mexican billionaire Carlos Slim said companies would do well to adopt his company's policy of working fewer than 30 hours a week, with retirement at age 75. 75? There's no typo? My folks are between 70 and 75. Despite not having had any serious physical/health problem in their life, I can guarantee they are not at all able to work any more. The decay in physical and mental abilities is too strong. Note that they don't lack energy however. But this big amount of energy cannot be turned in practical work any more.
