As a modern human, you should live to about 90 years old. But if you live in the U.S., your life expectancy is 78. What happened to those twelve years? They are mostly lost to chronic illnesses such as heart attacks, diabetes and cancer.
To change the equation you might want to consider a move to an area that has better longevity numbers (they are called Blue Zones) such as Ikaria, Greece where people tend to live a lot longer.
