Yeah, that’s the scary part. I’m not sure anyone really understands the media storm they’ll be walking into if they win. The smart folks get a plan and advisory team together, decline the press conference with the big check and get a head start on disappearing after collecting the prize. The nitwits believe they can resume their normal lives when the initial hubbub dies down, and can’t believe people are still accosting them years later and demanding a handout.
I think most people's natural instinct is to cash in the ticket before something can happen to it; the dog eats it, the neighbor steals it. "Just get the money in the bank and we'll deal with the rest as it happens."
This amount of money is going to completely upend someone's life, unless Taylor Swift wins it. She could probably handle it.
