Problem with that in the US is that there are only like 5 states that allow the winners to not be announced publicly.
The lotto winners going broke is actually a lot more common than people realize. Now granted, not all of them are huge multi-million dollar winners. The problem is they look at it as a time to do whatever the fuck they want, and after it's all said and done the tax man bites them in the ass.
I don't play the lotto much, but I had already decided if I were ever to win big, 100+million lump sum after taxes is what I consider big, I would invest 40%, stash away 40% to continue investments over the next 10 years, and keep the remaining 20% to live on. Honestly, I'd likely spend my days just traveling wherever I wanted for months at a time. Not like first class, high roller travel, just travel and enjoy the world.
