How Significant Is the Macro Economy to People's Portfolios?

This is my 40th year that's amazing. I have amazed myself sometimes and you're going to stay for how long are you going to go for the full 50s? Well I don't know actually they have a very good program if before 70 you can do a reduced load at Wharton. Barry has taught over 10,000 students in the 44 years he've been teaching. He'll be on reduced teaching for a few years probably four or five years and then you know settle back after that.
