Why do lottery players think they can defy odds?
"It's some version of ''What's the harm? I wouldn't want to be the idiot who didn't play the Mega Millions. What if I was the winner?'" Risen says. "It's a better safe-than-sorry philosophy: 'I'd better buy a lottery ticket just in case I was going to the winner.'"
Kathy Malzewski, a 67-year-old retiree from Milwaukee, never buys Mega Million tickets. But while she was in a grocery store Monday, buying scratch-off tickets as stocking stuffers, she decided on a whim to buy a single ticket because of the enormous jackpot.
What would she do if she won?
"I'd go into a nice retirement community myself, but I'd be generous," she said softly. "I'd help Habitat for Humanity, help the homeless, give a lot to charity."
Malzewski also said she'd travel around the United States. She saw the ocean for the first time in May and recently visited the Grand Canyon. She'd like to go to New York or Florida's Everglades as well.
"Why not?" she said with a smile. "There are so many places to see."
She'll know Tuesday night if she has an instant way to finance those dreams.
"I'm not lucky. I never win anything," she says. "But I might today. A person always has a little hope."
