As people live longer, more of them are also working longer—sometimes because they have to, but frequently because they want to.

A study from the Pew Research Center found that 38 percent of participants age 62 or older say they may delay their retirement because of the current recession. However, 54 percent of employees 65+ say they’re still working because they want to.

The oldest working American may be Jack Borden, a 101-year-old Texas lawyer.

According to the CNN Web site, Borden continues to put in a 40-hour work week, arriving at his office at 6:30 most mornings and working until about 4 p.m. (though he takes a 45-minute nap in the afternoon, per his doctor’s instructions).
