WIRED・2 minutes read
Biological age differs from chronological age, offering hope to slow or reverse aging. Women tend to live longer than men, facing risks like frailty, Alzheimer's, and osteoporosis. Aging is a complex system affected by molecular changes accumulating over time.
Insights
- Biological age, distinct from chronological age, presents an opportunity to potentially slow or reverse the aging process, offering hope for interventions that target underlying molecular changes.
- While genetics play a role in longevity, only influencing 10-20% of lifespan, lifestyle factors such as diet and exercise have a significant impact on health span, emphasizing the importance of healthy habits for aging well and preventing age-related diseases.

Recent questions
How does biological age differ from chronological age?
Biological age differs from chronological age as it reflects the actual aging process of an individual's body rather than just the number of years they have lived. This difference offers hope for interventions to slow or reverse aging by targeting the underlying biological changes that occur over time.
Are plant-based diets linked to longevity?
Yes, plant-based diets are indeed linked to longevity and disease prevention, supported by evidence. Choosing a diet rich in plant-based foods can contribute to a longer and healthier life by providing essential nutrients and reducing the risk of chronic diseases associated with aging.
Can aging be slowed or reversed in cells?
Aging can be slowed or reversed in cells, but halting the process entirely is challenging due to the complex nature of the aging process. Researchers are exploring various interventions to target cellular aging and potentially extend healthy lifespan, but complete reversal remains a significant scientific challenge.
How do women's lifespans compare to men's?
Women tend to live longer than men, facing risks like frailty, Alzheimer's, and osteoporosis as they age. This difference in lifespan can be attributed to various factors, including biological, genetic, and lifestyle influences that impact the aging process differently in men and women.
Is calorie restriction effective for longevity?
Calorie restriction may not be effective for all organisms, as some may experience shorter lifespans when restricting calories. However, exercise has shown limited lifespan benefits but significantly improves health span, which is crucial for longevity. This highlights the importance of adopting a balanced approach to diet and exercise for healthy aging and longevity.

"Exercise over calorie restriction for longevity"
- Calorie restriction may not be effective for all organisms, with some experiencing shorter lifespans when restricting calories. Exercise, however, has shown limited lifespan benefits but significantly improves health span, which is more crucial for longevity. The modern American diet can lead to pre-diabetic irritability and accelerated brain aging, emphasizing the need to change dietary habits for healthier aging. Medical advancements have increased life expectancy, but the rise in dementia, cognitive impairment, and Alzheimer's highlights the importance of focusing on health span extension rather than just lifespan extension to ensure a better quality of life.
