The Science of Aging: Debunking the Myths

Aging is a complex process involving genetics and environmental factors. No scientific evidence supports the perpetual youth depicted in 'The Age of Adaline'.

Telomeres protect chromosome ends, their length influences cell aging. However, no known mechanism halts their shortening indefinitely, as suggested in the film.

Caloric restriction has shown lifespan extension in animal models. Yet, this evidence is inconclusive in humans and doesn't imply immortality as shown in the movie.

Gene editing, like CRISPR, offers potential in combating aging-related diseases. Still, it is far from the fictional permanent youth achieved by Adaline.

Some species exhibit biological immortality, like the jellyfish Turritopsis dohrnii. However, transferring such traits to humans remains within the realm of science fiction.

Exposure to cosmic rays during space travel can accelerate aging, countering the idea of preserving youth in space.
