I read about a lot of people that became broke and lost everything within 5 years of winning millions of dollars in the lottery. Some of them ended up owing a lot of money and some of them committed suicide. So I would put it all in the bank and live off the interest. A lot of it would go into guaranteed investment certificates. As far as spending the money I would buy some nice things but try to keep my living expenses low. That way I could quit working for money and spend some time traveling. I would keep myself busy by traveling, taking pictures, writing articles and answering questions. And what would you do with this big big sum?
