So our bodies may be younger than we think. According to this New York Times article (free registration required), most of the cells in our body may only be seven to ten years old. Why don’t we act the age of our cells? The cells in our cerebral cortex don’t follow this process, so, mentally, we age.

This body may be composed of cells between seven and ten years old, but they certainly have mutated nearly beyond recognition from what they were fifteen to twenty-five years ago. The last two batches didn’t fare so well in the renewal process. I suppose somebody is working on that?

But all kidding aside, there are some fascinating ideas broached and discussed in this article. Check it out.
