====Medical intervention in the aging process====
Singer supports the view that medical intervention into the ageing process would do more to improve human life than research on therapies for specific chronic diseases in the developed world. He stated:

{{cquote|In developed countries, aging is the ultimate cause of 90 per cent of all human deaths. Thus, treating aging is a form of preventive medicine for all of the diseases of old age. Moreover, even before aging leads to our death, it reduces our capacity to enjoy our lives and to contribute positively to the lives of others. So, instead of targeting specific diseases that are much more likely to occur when people have reached a certain age, wouldn't a better strategy be to try to forestall or repair the damage done to our bodies by the aging process?<ref name="Singer-2012">{{cite news |last1=Singer |first1=Peter |title=Should we live to 1,000? |url=https://www.theglobeandmail.com/opinion/should-we-live-to-1000/article6657495/ |access-date=4 June 2021 |work=[[The Globe and Mail]] |date=December 27, 2012 |archive-date=21 June 2023 |archive-url=https://web.archive.org/web/20230621035807/https://www.theglobeandmail.com/opinion/should-we-live-to-1000/article6657495/ |url-status=live}}</ref>}}

Singer worries that "If we discover how to slow aging, we might have a world in which the poor majority must face death at a time when members of the rich minority are only a 10th of the way through their expected lifespans", thus risking that "overcoming aging will increase the stock of injustice in the world".<ref name="Singer-2012"/> Singer cautiously highlights that as with other medical developments, they would reach the more economically disadvantaged over time once developed, whereas they can never do so if they are not.<ref name="Singer-2012"/> As to the concern that longer lives might contribute to [[overpopulation]], Singer notes that "success in overcoming aging could itself ... delay or eliminate [[menopause]], enabling women to have their first children much later than they can now" and thus slowing the birth rate, and also that technology may reduce the consequences of rising human populations by (for instance) enabling more zero-greenhouse gas energy sources.<ref name="Singer-2012"/>

In 2012, Singer's department sponsored the "Science and Ethics of Eliminating Aging" seminar at Princeton.<ref>{{cite news |last1=Wang |first1=Angela |title=Scholar on aging argues people can now live to 1,000 |url=https://www.dailyprincetonian.com/article/2012/10/scholar-on-aging-argues-people-can-now-live-to-1000 |access-date=5 June 2021 |work=[[The Daily Princetonian]] |date=October 4, 2012 |archive-date=20 June 2023 |archive-url=https://web.archive.org/web/20230620231505/https://www.dailyprincetonian.com/article/2012/10/scholar-on-aging-argues-people-can-now-live-to-1000 |url-status=live}}</ref>
