There is a lot of talk going around about people who won't be able to retire because of inadequate savings.

The survey says it's "possible that health will initially improve when somebody retires and then, after a while, start to deteriorate due to reduced physical activity and social interaction."

The survey finds that retirement lowers the chances of staying in "very good" or "excellent" self-assessed health by about 40 percent. Retirement raises the odds of suffering from a diagnosed physical condition by about 60 percent.

And retirement increases the chances of contracting clinical depression by about 40 percent, according to the survey.

On the financial side, waiting until the age of 70 to retire will lift your Social Security income by more than 30 percent, according to the Journal of Financial Planning.

Meanwhile, a recent U.S. News & World Report story cites five retirement penalties you should avoid:

•  the IRA early withdrawal penalty,
•  the 401(k) early withdrawal penalty,
•  the penalty for failing to take required distributions from your IRA and 401(k),
•  the penalty for beginning your Social Security payments early,
•  the penalty for late enrollment in Medicare.
