life expectancy

so how do the japanese live 'til 85? well it surely isn't by eating a roll and sausage (red sauce optional) washed down with a can of Irn-bru for breakfast, steakbake and doughnut from greggs finished of by a harry ramsdens for dinner.
here's a picture from our local building site. so these are what you could say are typical japanese blokes in typical construction jobs. would you see a 20 minute warm up routine before site work in the UK? I wonder if there'd be industrial action if they tried to implement it. whats the use anyway, why should I have to? well I'm not privvy to governement figures but I'm pretty sure there would be less aches, pains and strains in the Japanese business. less days off and probably less accidents. and these guys hardly make a noise together never mind wolf-whistling. they don't even wear steel toe caps, but actually I'm not sure thats such a good item to lose. It certainly makes you more agile when you're crawling around scaffolding 20 storeys up though? anyway - maybe its samll things like this that makes the life expectancy in japan just that bit higher.
