I would use the money to build an Obamacare website. (if it’s enough)
I do not need a new house, or car. Would just pay off both of my houses. I have already traveled the world over, and have a life time supply of airline miles, and hotel points. Don’t have any unmet needs, I have traveled everywhere I want to go, so as long as I have enough money to keep my ‘66 landcruiser maintained, and fueled, and stocked with spare parts, liquor, food, and all weather of camping gear I will be happy to just wander the deserts of Nevada, Utah, New Mexico and Arizona until my body stops working.
