The health problems of Jobs and other CEOs are still a personal issue and one that shouldn’t concern investors so much.

First, a company is never dependent on one person, no matter how it may appear. Assets, brand names and a corporate culture should prove durable even when the person who created them departs. If a company relies on the health of a single person, you should sell the shares right away. Nobody is immortal, so the equity is going to collapse one day.
