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.

Is the older a patient is more sensitive to radiation they become? A review of age and radiosensitivity

Recent studies suggest a bimodal distribution of radiosensitivity throughout a person's life, with increased sensitivity at very young and older ages. This challenges the long-held misconception that older patients are less sensitive, prompting a deeper look into the intricate cellular and physiological changes that address the question, "Is the older a patient is more sensitive to radiation they become?".

What is the error theory of aging?

Approximately 36,000 to 160,000 DNA lesions occur per cell per day in mice, demonstrating the constant molecular challenge within an organism. This notion of accumulating damage is central to answering the question: what is the error theory of aging, a concept that attributes aging to progressive, non-programmed cellular mistakes.
