At 55 years old, I will have worked for 30 years — what are the pros and cons of retiring at that age? 

Dear MarketWatch, 

I currently own one home, no mortgage with rental income. I own another home that will be paid off the year I turn 55. Both valued at $750,000.  I have a 401(k) and other stocks and investments totaling another $750,000. My debt will be all paid by the year I turn 55.  

I have been on my job for 27 years. It will be 30 years…
