The largest jackpot in US history...pretty exciting. However, a large, unexpected windfall can be more of a curse than a blessing. Winners have faced a variety of personal and financial challenges...and not always for the better. A common story is that the winner ends up going broke.

The deeper and more troubling is that winning can change the nature of personal relationships. Spouses may disagree about how to spend prize money and get divorced. It can also alienate winners from friends, family members and co-workers.

Many people enter into pools with friends or co-workers who intend to split winnings. However, this can cause more issues, if it's not made crystal clear about who's in and who's not.

That being said, I've got my ticket...you?
