Today, scientists have begun determining a cell’s biological age – meaning how well it functions and not how old it literally is – by measuring the length of its telomores.
In case you don’t know every portion of our cells’ interiors, telomeres are tiny caps found on the end of DNA strands, like plastic aglets on our shoelaces. They protect the DNA from damage.
As a cell ages, its telomeres shorten and fray (are tiny caps found on the end of DNA strands, like plastic aglets on our shoelaces). They protect the DNA from damage.. Many things can advance the damage, i.e. obesity, smoking, insomnia, etc. However, a recent study at the University of Mississippi and University of California, San Francisco have found exercise may slow this process.
