The oldest human cells?

Fifty years ago, a Norwegian man named Bernt Aune received a cornea transplant from a man born in 1885. Today, Mr. Aune is 80. His cornea works works fine. It is 123 years old.

For details, see this. Somehow those cells did not degrade with age, as one might expect. Some think this phenomenon, should we come to understand it, could be a key to stopping aging. Good idea? Or a futile attempt at eternal life on our terms?
