Re: Being of average chronotype

There's an article in this week's New Scientist on a correlation with a
desire to smoke and a misaligned body clock, what's known as "social
jetlag".

This article introduced me to a new word: chronotype. This is a measure
of what your ideal hours of sleep are. There's apparently a wide spread
and "the latest owls are still up when the earliest larks are rising."
However, findings have shown that the average person prefers to sleep
from 12:30 to 8:30 a.m.

This intrigued me, as since my retirement and no urgency in getting up
most mornings, these are almost exactly the hours I do sleep. However,
the article doesn't say whether this is clock time or solar time. The
clocks went forward last weekend and I didn't manage to get up till
08:45 this morning.

Then there are those of us who are different. My sister and I need only
six hours of sleep per night, a trait we inherited from our father. My
brother is probably like this as well, but I haven't asked him.
