How did we get from an age 40 life expectancy in 1815 to a 90 year old life expectancy now?

This is a very important question because the answer here is also how we get to 150 to 200 years of age and beyond.

The answer is education, diet, exercise and enlightenment (in other words to become wise in all ways as a human being) including regarding psychological and spiritual things.

The more you know and the more you can live of what you learn and know, the longer you will choose to live and the longer the lifespans of mankind will be. As people live longer often they also will be wiser and by becoming wiser, if younger people listen to the wisest of us, their lifespans will slowly increase too more and more and more.

This is our future now, just as it was the future of our ancestors to go from an age 40 lifespan then to an age 90 lifespan now here in the U.S.

In other words: "If you live to be 30 you likely will also live to be 90".

This is the actual state of affairs statistically here in the U.S.

It doesn't mean this will happen to you but it is an average of people in the U.S.

From my point of view the real test is just living to 30 while still sane and physically healthy,

this is the real test of a human being.
