Researchers reveal that the continuous increase in life expectancy observed in the 20th century may be slowing down. This period marked a turning point, with notable improvements thanks to medicine and effective health policies. The idea that we could generally live to one hundred years or more may prove to be an illusion.

Nature Aging has brought this situation to light. Researchers from the University of Illinois examined data from eight countries with high life expectancies. The results show a slow decline in improvements since 1990. The promise of a longer and healthier life is facing new challenges.
Experts note that only 5% of men and 15% of women could become centenarians this century. Inequality in access to healthcare and medical innovations plays a significant role in this trend. Developed countries are not all equally positioned on this issue.
The analysis of statistics reveals that Hong Kong and South Korea stand out with higher life expectancies. These countries have succeeded in extending their populations' lifespans, but this comes at a cost. Other regions, like the United States, show a decline in life expectancy.
Researchers emphasize the need to slow down the aging process. Medical advancements are still possible, but concerted efforts must be made to improve the quality of life for the elderly. The focus should be on a proactive, prevention-based approach.
The numbers concerning longevity are undeniable. Predictions show that most children born recently will not live to 100 years. This reality echoes a broader trend, that of unequal distribution of resources and innovations in public health.
The debate on the limits of human longevity is far from settled. While some envision a bright future where immortality could become a possibility, current reality seems to remind us of our biological limitations. Life expectancy may have reached a plateau.
Researchers call for caution. They believe we may have reached our maximum, unless we break through this glass ceiling. Ultimately, the potential for a new longevity revolution will depend on advances in understanding aging.
