Re: traditional navigators
I wonder if Polynesian navigators of old could hear the sound of surf carried long distance by the water more so than by the air. That would help locating the nearby island. But I think they just had bigger balls and were not shying away from big risk journeys. None of us would even think of hunting grizzly bears with a spear, yet people used to do that long time ago.
Be kind, for everyone you meet is fighting a hard battle.
