Aging and longevity news covering geroscience, senior care, Medicare policy, and healthy lifespan research.
A new mathematical model published in npj Aging suggests that if all reversible aging hallmarks except somatic mutations were eliminated, humans could theoretically live up to 156 years. The model identifies neurons and cardiomyocytes as the main limiting factors.
Dr. Ezekiel Emanuel argues that healthy aging can be simplified into six evidence-based rules, including avoiding dangerous activities, prioritizing social connections, and limiting processed foods. He contends that society's obsession with wellness is misguided and that living a meaningful life is more important than self-denial.
Researchers found that restoring the ability to clear senescent cells prevented cognitive decline and frailty in older mice. Blocking the EP2 receptor, either genetically or with an experimental drug, reduced inflammation and improved mobility and memory, hinting at potential human therapies.
This commentary explains why appetite decreases with age, citing hormonal shifts, diminished senses, and muscle loss. It argues that these physiological changes are normal and offers practical advice for maintaining nutrition in older adults.
This commentary argues that walking speed should be considered a vital sign for health, citing links to dementia, heart disease, and mortality. It provides a simple test for readers to measure their own walking speed and offers advice on improvement, based on expert sources.
This commentary argues that visiting museums and engaging with art can have significant health benefits, potentially contributing to a longer life. It uses a personal anecdote about a 90-year-old friend who experiences mood improvements from museum visits to illustrate the positive impact of cultural engagement on well-being.
This commentary argues that demographic aging is manageable with policy adaptation, citing positive developments in defense, climate, and Social Security. It suggests that proactive measures can turn challenges into opportunities, countering alarmist narratives about an aging population.
This commentary argues that engaging in cultural activities like visiting museums or attending concerts can slow physiological aging. It cites a study showing that adults who participate in such activities every few months have a lower physiological age than those who do not, suggesting lifestyle choices can influence aging beyond chronological age.
This commentary argues that avoiding comfort and embracing new challenges is key to healthy aging, citing the concept of hormesis. It suggests that mild stressors like varied exercise and plant compounds build resilience, though evidence primarily supports improved health rather than extended lifespan.
The author reflects on her own impending senior status and examines internalized ageism, arguing that psychological flexibility is key to avoiding rigid thinking. She recounts a personal anecdote about a dismissive cardiologist to illustrate how ageist attitudes can persist even among professionals, urging readers to challenge stereotypes.
