The Wealthiest Americans' Top Worry Is ...

What's left to worry about when money is no object? Health, apparently. According to a report from two financial-advisory groups, American millionaires with a net worth up to $25 million rank their spouse's health as their number-one concern, Business Insider reports. Those who are merely affluent—with $100,000 to $1 million in net worth—are most concerned about keeping up their current financial position, followed by that of their children and grandchildren. But their next five top-ranking concerns are all health-related:

• The health of my spouse
• My own health
• Family health catastrophe
• Spending my final years in a care facility
• Having someone to care for me in my old age

And there are more of them to worry, Time reports: A record 9.63 million US households had a net worth of at least $1 million last year—58% more than in 2008—and those making $100,000 to $1 million also rose over the year before. (Click to see how many members of Congress are millionaires.)
