Can you pls elaborate on the 10 degrees and 15 degrees? I don't know geometry or math. How exactly do you hold out your arm against the sun? At what angle to the sun? Illustrations appreciated please!
Spot on. Getting a routine is absolutely critical. You can sense the passing of time by watching the movement of the sun. So if you put your arm out -- and this is the same for all of us, 'cause our hands and our arms are about the right proportion -- that's 10 degrees, which is just under an hour. 15 degrees is how much the sun moves in an hour. So you know that you've got as many of those as it is for the time of year before sunrise and sunset. So there are things you can do to keep track of time.
