Day 12
The Wall Street Journal today published an article citing several studies which have found seven hours sleep per night is probably optimal for health and wellbeing.  This is one hour less than the previous recommendation of eight hours but still more than most Americans probably get most nights.  Can we assume the same statistic applies to New Zealanders? - probably, if I'm anything to go by.  Yawn.
Happily, when indulging, scientists have reassured us that we can rest easy in the knowledge that it's impossible to overdose.  We just wake up when we're done.  Amazingly physical truisms like this, taken for granted by my mother and all those who came before her, now require scientific verification. But since we have it, I'm going off for a seven hour nap.
