re: do these people plan to work forever?

I have a coworker who has zero money in retirement and could not afford to pay off a $2000.00 hospital bill from his savings. He said he pays $20 a month on it. I asked him how is he going to retire and he said he will work until he dies. He just turned 65 and is enjoying using Medicare since he has not had health insurance the last 20 years. His yearly income is in the 50k range and he lives pay check to pay check.

Some people baffle me.
