Your Body Is Younger Than You Think

Topics: Medicine

In fact, most of your body is a lot younger than you think, but there's a catch - the key is most, but not all. Most cells are renewed, but than there's the little matter that we do have brains and they are made up of cells (although sometimes I question the existence of that particular organ in some of our friends on the left), and at least some of our brain cells within the cerebral cortex(particularly the visual cortex) are with us from birth to death.

Yet, with the possible exception of Daily Kos aficionados lacking grey matter and having no grey matter to renew, regardless of your chronological age, most cells in your body are many years younger. In fact, even if you're middle aged, most of you may be just 10 years old or less. That's because most of our body's tissues are under constant renewal, and this fact has now been underlined by a novel method of estimating the age of human cells, thanks to it's inventor, Jonas Frisen, who believes that the average age of all the cells in an adult's body may turn out to be as young as 7 to 10 years.
