Hank Greenberg, Chairman and Chief Executive Officer, C.V. Starr & Co.

I am addicted to exercise. It is a good habit. I usually exercise in the evening except on weekends. I find exercise after work unwinds me. On weekends, in the spring, summer, and fall, I play tennis and in the winter, if conditions permit, I ski. Anyone running an organization such as C. V. Starr needs to be in good shape physically as well as mentally.
