interesting discussion. It may be that we do have a similar sensing mechanism like that of migrating birds and animals that use the earth's magnetic field but it could be so underdeveloped that it's jsut not evident.. Would be more interesting if somebody comes up with that developed instinct and prove that is actually true..
Not that it solves any of humanity's problems today, but that'll be a cool funciton to have especially when you get lost and don't know which way is north :)
This is an awesome contribution to the subject of discussion. Thanks for this insightful comment. Do steem on.
