I wish I had the ability to survive on as little sleep as the people on here. I cannot function without at least 5 hours of sleep. And yet, I constantly get only around 3.5.

It's not even that I'm doing something interesting so late at night.

If people on here are getting by on 5h sleep, they've either got unusual metabolisms (it happens, but it's rare), or more likely, they're permanently in zombie mode.

I'm capable of functioning on 3~4h, but I'm not going to get much done, or be pleasant to work with, on any less than 7~8h.
