Yoda The Mouse Turns 4

ChiralSoftware writes "Through some genetic engineering to reduce insulin output, Yoda the mouse has lived to over four years old, equivalent to 136 human years. Yoda is a third smaller than normal, and gets cold all the time so he must snuggle up with Princess Leia, his cage-mate, but he is alive and full of vigor at the ripe old age of 4. Who's next for insulin reduction?"
