How long do you think you'll live? New research suggests you can tack a few more years on to whatever number you came up with. In 1992, University of Michigan researchers asked 26,000 Americans between the ages of 51 and 61 if they thought they would make it to 75.
Some 22 years later, researchers with the Brookings Institution crunched the data and found people tend to underestimate how many years they have left. Of those born between 1931 and 1934, a full 49% who said they wouldn't see 75 were wrong.
