Researchers explore cell manipulations, young blood transfusions, and dietary compounds in extending lifespan. They discuss the oldest person Jeanne Calment, natural limits to lifespan, and exceptions like immortal jellyfish. The impact of rapamycin, young blood, and lifestyle on aging is also examined.
Researchers are exploring cell manipulations and young blood transfusions to understand aging biology.
Finding chemical compounds that mimic low-calorie diets show promise in slowing cellular aging.

Natural Limit to Human Lifespan
Researchers are investigating cell manipulations, transfusions of young blood, and chemical compounds that can mimic low-calorie diets to understand the biological underpinnings of aging. The oldest verified person lived to be 122, sparking discussions about the potential natural limit to human lifespan. Evolutionary biology suggests that larger species tend to live longer to maximize reproductive potential. Some species seem exempt from this rule, hinting at the possibility of circumventing natural limits to aging.
Research on Anti-Aging Strategies
Scientists are exploring ways to manipulate cellular aging, including destroying senescent cells and reprogramming cells to revert to an earlier state of development. Research focuses on finding chemical compounds that mimic the effects of a low-calorie diet, such as rapamycin. Studies also show rejuvenating effects of young blood on old bodies. While longevity research is promising, basic health practices like moderate eating, healthy diets, sleep, and exercise remain crucial for healthy aging.
