What are good warning signs to watch for that can signal a retirement

[PatrickR720159]

Some employers may feel when a person reaches his or her 70s that means it is time for retirement.  But some still feel that their bodies will let them continue working until they reach their 90s or get into their early 100s.  Not many people reach that age.  What are some good warning signs health wise that many of us that are still on the job that we have to keep a sharp eye out for?  I know that sometimes when it comes to shortness of breath while on the clock hits too often, that could signal a retirement.
