Good morning!
Some people are really satisfied with what they are doing and for me it is better than doing well and having good job or income but not satisfied with your job/work. I just recently saw this video clip of "Neil deGrasse Tyson" saying if you want to be happy do something (as a career) which you would happily do for free.
I don't know that old man's motivation but as you said he could just be very comfortable and don't want to look for something else. So many different personalities all around us!
