But when people pick a career that they want to do or think about, the kids who go to college for a career, you don't invest that much time and money to only step down after 20 years into it because your getting older and slower. That will happen to all of us. That's why you work to retirement.....Not to step aside when some young stud comes in. You will not find a new job to start at that age. You keep what you got and hope you can make it to your retirement.
