Is there real evidence for this?

There is some discussion in the Washington Post (http://www.washingtonpost.com/wp-dyn/content/article/2005/10...) from 2005.

Here is some stuff about it on WebMD (http://www.webmd.com/sleep-disorders/guide/important-sleep-h...). This one does not outright link it to death, but many things which help death come knocking.

I thought this was well known, so sorry about the lack of links in the first assertion. Is that why I'm gaining negative marks, or are you shooting the messenger for the news you don't like?

At least in the extreme. If you do not sleep at all.

In the extreme, eating can kill you also :/
