Increasing longevity increases population 1.2.9

The population of China is 1.3 billion. The life expectancy is 73 years. The longevity of the 10 healthiest countries is 80. This means that when China achieves modern health, its longevity will increase 7 years. Assume that China achieved a replacement birth plan and then its longevity increased. The population of China would go up ~10% or increase by 130 million people. For each additional year in longevity China's population would increase 13 million.

For a country like Nigeria with a population of 150 million, with the same stable birth plan inplace and present longevity of 46 the population could almost double based just on change in life expectancy.

Even 80 is not the expected top longevity of humans. Better living and health care have been extending longevity 2.5 years per decade. That is when a person lives 10 more years, and is attended to my modern medicine, the addition to his longgevity is 2.5 years. That means total population could expand an additional 3% each decade with a replacement birth plan.

Ray Kurzweil, author of "The Singularity is Near" and "Live (long enough to) Forever foresees a time (20-30 years in the future) when the combination of fast computer processing (artificial inelegance,) miniaturization (nano technology) and gene splicing will combine to improve the doctor's skills to replace worn out parts and keep old one's working, that for every year you live you can add on an extra year. In effect no one dies.

This a quantum change, It means, with no one dying of disease or old age the population would grow at the rate kids were being born. If we wanted a stable population, no kids cold be born at all!
