Dear Marina, great article. Love that you also looked into the Blue Zones, something I'm super interested in myself. I try to live my life according to the Ikigai concept - and found that quality might be more important than quantity in the end. My thoughts on quantity ended with the whole cryonics industry, which could cover another article on this very same topic. If you're not happy with the quality of life extension in the 21st century, why not obt for cryonics? Cheers! Matt
