I need 9-10 hours sleep a night. It's a lot, right?

I wish I could cut down.
I wish I could think: Sharks don't sleep!! I'm a kick-ass street-fightin' man with Napalm in my veins and Giddy-Up-Horsey in my nether regions.

I wish I could eschew sleep, and instead dynamically "Catch some Zs"

Maybe I would be a gazillionaire instead of a sleepyhead, which, let's face it, is what I am now.

But, I can't.

How much sleep do you need?
