As well he shouldn’t.
Retirement is over-rated, plus he’ll probably run circles around the Gen Xers who think they can match his skills.
He’s fortunate to have an amazing mind....Einstein type....and like most people with brilliant minds they can talk your ear off because they enjoy hearing themselves speak. Therefore you always learn something valuable when they do.
He complains all the time about Gen Xers and others who are not focused on their work and do the least amount necessary.....since he’s always had a home office much of his work when off the road is dependent on communication with the main office as well as clients.....so it can be frustrating for him when people drop the ball.
