What would you do if you won $43 million?

New house, flash car, holiday, private jet – the options are almost limitless.

But 90-year-old Florida woman Ruby Sorah was determined a lotto win would not change her or her husband’s lifestyle – so she decided to give the entire sum away.

• $27.75 million for a day’s work? Not bad…

Mrs Sorah decided to take her winnings in a lump sum payment of $US31,042,330 ($A43.5 million), and she declared she would give her newfound fortune to her family.

The couple bought the winning ticket from a Winn-Dixie supermarket in Seminole, and on it were all six winning numbers.

Neighbours of the couple said they are rarely sighted and that Mrs Sorah’s husband only ventures out to check the mail and mow the lawn.

Rick O’Callaghan, whose brother lives opposite the Sorahs, said the couple was very down to earth.

“It’s great,” he told Fox 13. “They’re the quietest, nicest, most reserved people you ever saw in your life.

“It’s heartwarming.”

While certainly being out of the ordinary, this is by no means the first time a big lotto winner has decided to give it all away.

In 2014, Roy Cockrum used most of his $259 million win – the largest in Tennesee history – to start the Roy Cockrum foundation, dedicated to helping non-profit theatres “reach beyond their normal scope of activities and undertake ambitious and creative productions”.

Scottish couple Chris and Colin Weir, meanwhile, gave up more than 80 per cent of their $249.8 million EuroMilions win to the Scottish independence movement.

And a Candian couple won more than $11 million in 2010, only to give it all away within five months to those less fortunate.

The winning wife had successfully beaten cancer, and a large part of the money was given to treatment centres – including the one where she was treated.

“There’s so much good being done with that money,” she said.
