Herbert Wertheim, born in 1939, was formerly an ophthalmologist and now owns over three billion dollars worth of stock, an investment he made approximately forty years ago. He doesn't need to do anything; he simply relaxes. He is the second-largest shareholder outside the founding family, but compared to the former, he is clearly more idle. Wealth (resource redundancy), health and longevity (physical redundancy), leisure (time redundancy), and deep thinking (knowledge redundancy) are all causally related and none can be neglected.
