Agreed, I chose US and UK because I live in UK, have family in US and find it interesting that the US has a shorter life expectancy. Blue Zones are interesting too as people regularly live to a very ripe and still active age. Personally I don't think we're any where near ready for this sort of life extension, neither as a society or as individuals. Pension age has risen in the UK and people are very cross that they have to work a few more years, imagine how they'd moan if they had to work until they were 80!!!!
