http://www.nytimes.com/2010/09/13/us/13aging.html?_r=1A study by the federal Bureau of Labor Statistics found that for workers ages 55 to 60, the share who said their jobs required “lots of physical effort” all or almost all of the time declined between 1992 and 2002, to 18 percent from 20 percent, but the percentages who said they had to lift heavy loads, stoop, kneel or crouch increased.
In 2002, 29 percent of workers ages 55 to 60 said they experienced chronic pain in their jobs, and 46 percent said they had arthritis.
And though more Americans are retiring early, it is not always voluntary. A 2006 study by McKinsey & Company found that 40 percent of early retirees said they were forced into it, about half for health reasons.
“If you try to punish people for retiring earlier” by raising the retirement age, “you’re punishing people who aren’t choosing it,” Professor Ghilarducci said.
This is not news to Jim McGuire, 62, a ramp serviceman for United Airlines, who started lifting bags into airplanes 43 years ago. He has had rotator cuff surgery and separated a shoulder on the job.
“From 50 to 60 was a drastic change,” he said. “The aches and pains, the feeling that your back could go at any second. My hips are worn out. In a seven-day week, I take Advil five nights for the pain.”
