Scientists Discover Parts of Our Bodies Age at Different Rates
Some people age faster than others, but the discovery of a DNA body clock by UCLA researchers now shows that different parts of our bodies age faster than others. The discovery offers important insights into the aging process — and what we might be able to do about it.
This isn’t the first time that biologists have developed a mechanism for assessing age. Earlier “biological clocks” have been derived from data drawn from saliva and hormones. More crucially, there are our telomeres to consider — those fraying tips of our chromosomes that have been linked to cellular expiry dates, and by virtue, our individual rates of aging.
