Thanks to a new drug, you may soon be able to be morbidly obese without it having any sort of detrimental impact on your lifespan. At least, if you're a mouse.

Here's some exciting news: Harvard researcher Ronald A. DePhinho has discovered a way to reverse age degeneration in mice, opening the door to the possibility of a similar process working on humans.
