How the heck do you find north based on your watch?
I live in north Manchester so I know Manchester is south
What if you go on a trip to Thailand and get turned around in the jungle?
Or I can look at the sun if not midday and figure it out
That gives you a very approximate direction.
You don’t need to stare directly into the ball of fire to determine where the Sun is. All you need is the flashes of light through the leaves - and you CAN see that in the jungle.
