Societal effects of negligible senescence

The term was introduced by biogerentologist Caleb Finch to denote organisms that do not exhibit evidence of biological aging and was further popularized by gerontologist Aubrey de Grey.

[5] Only a few people have publicly announced that they deem negligible senescence likely in the 21st century, such as Aubrey de Grey, founder of the SENS Research Foundation.

[6][7] Coale noted that a shift toward near-immortality would have the same long-term impact on population growth as a 10% increase in the fertility rate.

However, this might be offset by no biological limitations on having an unlimited number of children (delay or complete eradication of menopause) which in turn may or may not occur with negligible senescence.

Furthermore, the age of mothers might increase or stay stable depending on a myriad of factors thus impacting TFR.

Therefore, the development of negligible senescence therapies have profoundly different effects on the economies of countries with different demographic characteristics.

[3] As philosopher Nick Bostrom mentioned in his story "The Fable of the Dragon-Tyrant" referring to the end of senescence: "And in the coming days...
