Hump Day Top 5 List: Celebrities Who Will Still Matter in 2020

Celebrity is ephemeral (that means "you won't be around much longer, Britney"), but here are five whom I think will be with us for a long time. Any other lists, serious or frivolous?

1. Bill Clinton - He's probably the most influential American not in the White House, and he'll only be 74 years old in 2020.

2. Charlize Theron - She seems to have the durability and skills to be active and important for a long time.

3. Steve Jobs - It's hard to stay cool, but he and his products have already been cool for more than 20 years. What's another 14?

4. Barack Obama - By then, maybe President Obama?

5. Bono - In 2020, his music will be the smallest part of his legacy.
