I sleep between 4-6hrs a day. It's been that way since I was in the Army. I know that "studies" have shown you need more sleep than that, but my body just does not like it when that happens. Almost all of my work is online, and I'm also the host/co-host of a few radio shows & podcasts, which involves a ton of promoting online. It's just the nature of my business. I'm also the oldest of 14, and live 3000 miles away from my family, so communication online is the only real way we talk.
