"I do believe if one keeps busy it's very good for a person. In fact, people are always rushing into retirement and we read in Europe that people there are talking about their retirement age and moving it to 67 or something. Well, back when they started retirement funds and everything, the average age was 70 or 60, and then all of a sudden now it's 80, and so. [...] And so you keep in shape, you keep yourself mentally in shape. And if you keep yourself mentally in shape, chances are physically it will follow suit."
