Antediluvian Patriarch and Sumerian King, (In) Bad-tibira(k) En-men-lu-Anna(k), according to the records he lived to be over 43,200 years old, of which he spent at least that long ruling the ancient Sumerians. While I have little interest in ruling anyone but myself, I would sincerely enjoy having that much time to continue learning. If a rulership presents itself during that time, I might give it a try, if it is properly incentivized.
