they are almost 70. I think the Blue Zones[1] make a pretty strong case for groups of people living with similarly healthy lifestyles all living longer than the average and with better quality of life. I just think it's pretty reasonable to conclude that there will be a difference between the bodies of people who take care of themselves over their lifetime vs. those who don't. We have people living longer and longer (I think the last person was 122?!) and it doesn't really make sense that you reach an age like 80 and everybody, no matter their choices, all end up similarly unhealthy and in pain with reduced mobility. 1. https://en.wikipedia.org/wiki/Blue_Zone https://en.wikipedia.org/wiki/Blue_Zone
