That's the only logical explanation i can come up with for this study to have even taken place.

Saul Villeda of Stanford University, who led the work, found that blood from young mice reversed some of the effects of ageing in the older mice, improving learning and memory to a level comparable with much younger animals. He said that the technique could one day help people stave off the worst effects of ageing, including conditions such as Alzheimer's.

And let me just say that starting off your article with "Kim Jong-il did it, too" doesn't exactly help your case.
