The bubonic plague was a painful disease, with black buboes, or swellings, in the groin and armpits, which lasted up to a week. There was some chance of surviving if the buboes burst.
As of 2015, full retirement age is 67 if you were born after 1960. The amount you receive doesn't change because disability benefits were calculated based on what you would receive at retirement age. However, you may see an increase if Social Security provides a cost of living increase.
For many of us -- people born between 1943 and 1954 -- our regular retirement age is 66. You're eligible to start receiving Social Security as early as age 62. But you suffer a penalty. You can also delay taking Social Security until age 70. Then you get a bonus. The penalty for taking Social Security early is a little over 7 percent a year, and the bonus for delaying is also slightly over 7 percent a year. So for example, if your normal retirement benefit at age 66 is calculated at the average of $1,233 a month, you'll only receive about 1,150 per month if you sign up at age 65.
