Scientists reverse ageing in elderly mice by rejuvenating their tissues
IndependentDec 23, 2021
The Facts
According to a study by Stanford University and Nanyang Technological University in Singapore published Wednesday in the journal Nature Aging, the human body's aging accelerates significantly around ages 44 and 60.
The peer-viewed study shows that people in their 40s and 60s experience pronounced physiological transformation, possibly fuelling age-related diseases.
The Spin
Narrative A
While scientists are making exciting discoveries about the biology of aging, the most effective anti-aging strategy remains simple — a balanced diet, regular exercise, and adequate rest. As we navigate this new frontier of extended lifespans, we're reminded that quality of life is as important as quantity.
Narrative B
As major discoveries are made about aging, the tantalizing possibilities for extending the human lifespan must nudge us to consider their moral implications regarding issues like overpopulation, resource strain, and societal inequality. Deeper philosophical questions surrounding mortality and life's meaning must also be handled with wisdom and foresight.
Narrative C
While halting aging might be theoretically possible, reversing it in humans is biologically unfeasible. This doesn't mean the end of anti-aging research as scientists will continue exploring ways to mitigate aging's harmful effects — even though true reversal remains elusive.
