Good for him, I'm glad he enjoys his time at his law practice... us 4 kids of his are going to need all the help we can get!
:D
I find a lot of people who retire, tend to go downhill faster than those who don't. Perhaps with all that time and no pressure, there is little will to actually learn anything new and stay sharp?
I think it has a lot to do with families and hobbies. As long as somebody has something to keep them motivated and active, I think they will do well as they get older. But those who have nothing to do or look forward to, those are the ones who will really struggle.
