How do some smokers live to 100? Genetics and other factors

While roughly half of all lifelong smokers will die from their habit, a small, biologically distinct group with exceptional longevity exists. For these individuals, the combination of genetic variants and other factors appears to provide significant protection against the environmental damage caused by long-term smoking, explaining how do some smokers live to 100.

What are some complex traits that show a paternal age effect?

The average age of first-time fathers has steadily increased over recent decades in many developed nations. This societal trend has brought significant attention to the complex traits that show a paternal age effect (PAE), a phenomenon where the biological father's age at conception is statistically linked to certain health outcomes in his offspring. The biological underpinnings, including genetic mutations and epigenetic changes, offer crucial insights into this association.

What age do you fully grow into your nose? The lifespan of nasal changes

While the bony structure of the nose typically stops growing during the late teens, the cartilage continues to change throughout life. This continuous development means the popular question, "What age do you fully grow into your nose?", has a nuanced answer, influenced by genetics, puberty, and the ongoing process of aging.

Understanding the 'Cholesterol Paradox': Do Most Centenarians Have High Cholesterol?

While high cholesterol is a primary concern for heart health across much of the population, studies on centenarians and other exceptionally long-lived individuals reveal a surprising truth. The question, "Do most centenarians have high cholesterol?" uncovers a complex relationship between lipids and extreme longevity that defies conventional wisdom.

What is the information theory of aging?

According to research published in *Nature*, the information theory of aging (ITOA) posits that aging is driven by the progressive loss of youthful epigenetic information. This conceptual framework suggests a paradigm shift in understanding why and how we age.

What is the metabolic theory of aging?

Decades of research in animals from worms to mice have shown that metabolism is a key factor in determining longevity. In the context of this broad finding, the metabolic theory of aging explores the intricate link between an organism's energy expenditure and its rate of aging, positing a direct relationship between the speed of metabolism and lifespan.
