Sleep is the cousin of death

Does not sleeping very much but not getting up early count?

I probably would want less sleep than even what I do get really. 3-4 hours should be enough. At worst, I'd like to get to where I can nap frequently to get that sleep instead of actually retiring for an evening or morning or whatever. It feels rather more useful, as with eating, to do so whenever one is responding to a stimulus to rest rather than at some appointed time. The inverse effect of this is probably the consumption of coffee and its effects on the brain (without even consuming it) to stay awake. I find it's better to just sleep or rest when you get tired than to try to stay awake with stimulants. Naturally, there are occasions where that isn't possible. Driving a car for example. A regular rhythm of sleeping/waking does establish some stimulus to rest, which is fine. It just seems like a waste of time to me.

What I'd be curious about is what caused the genetic change and what, if any, trade-offs there are for not getting more rest and sleep relative to others. It seems like such people are more productive or efficient through the day anyway. What's the downside, any health complications, do non-sleepers/early risers die sooner or something?
