Some guys just can't slow down. Take Julian Myers. At age 90, he still runs six days a week, operates his PR agency in Marina del Rey and figures he'll live to 120. "I'm confident I'll pick up clients till the end," he said.

What do you do when you turn 65? Most retire, but many successful Angelenos keep on working just as hard as ever. Or they started a business. Or two. In fact, some work even harder. For example, Al Mann is 83 but typically works 12 hours a day and sometimes 80 hours a week.
