Average Life Expectancy myths?

Most of the modern increase in life expectancy is due to improvements in infant mortality. If you made it past childhood in the old days you had a fairly good chance to live a long life. I am not sure what the adjusted year to year life expectancy would be, if you factored out infant mortality, say going back about a 100 years ago. Anyone?

nobody said its the body. its advances in medicine, better living conditions etc.

One, considered the major, key to increased longevity would be modern antibiotics. Refrigeration and improved sanitation would play secondary roles.

I have seen a few images of stats of things like polio actually decreasing years before vaccine for it is introduced.

It's not that I don't believe you, but do you have any references for the polio reduction?

all i did was google image search disease vaccination chart or something like that and seen some charts that way.. im not sure of the exact wording I used to search though

Lots of things contribute to life expectancy.

Here are some reasons people died younger:

1 Poor diet. You only ate things in season. Today we eat
all kinds of things all year around because of
refrigeration and world trade. As in some parts of the
world today food is inadequate, bad and sometimes
unfordable as it used to be all over. Starvation was
much more common.

2 Sanitation. Most of the world did not have indoor
pluming of any sort 100 years ago. In many cities you
simply emptied your chamber pot in the street. If you
were lucky you got to bathe once a month. Water was not
treated as it is today and a lot of the water was bad.
An outhouse just emptied into a hole. Eventually you
you had to dig a new hole and move the outhouse.

3 Medicine. 100 years ago doctors in many areas were
non existent. The idea of germs was not known
so if you had some sort of medical procedure you were
likely to die from infection. Before modern medicine if
you were injured there was a good chance you would die
from infection. If you got sick there was a good chance
you would die.

4 A lot of women died in child birth and a lot of children
never lived until adulthood.

For most of us it is hard to imagine what life used to be like. Before railroads most people walked everywhere as few people could afford a horse. Most people could not afford candles or other forms of lighting. Glass was a luxury few could afford so most people had blankets or pieces of leather in windows. Life was hard for most. The modern idea of minimum wages and welfare was non existent. The whole family lived in one house their whole life and many houses had one bed in one small bedroom, if they had a bedroom. Several hundred years ago if you were a common person you probably only had one pair of shoes and two sets of clothing, one set of clothing for everyday and another set for special occasions which is how a lot of people live today in more backward places. Long life was a privilege of wealth.

Yes I agree with all of those but what I'm getting at mainly is people try to contribute the younger death rate with introduction of vaccines yet I have seen evidence on the contrary

Factoring out early life failures, the big issues for seniors staying active and healthy for the longest life are the same. Minimal infections, minimal inflammation, low carb diet, restricted diet, pro-dopamine drugs and habits, and a high level of physical activity are necessary.

Avoidance of MDs and hospitals is mandatory. Having no "health insurance" is a plus.

There should be no incentive to die or be ill. Insurance does that kind of thing.
