Date or Hate

Hate!

I'm totally outdoorsy spent like a gizzillion Rands (about 10 USD ) getting my lover to take me where I want to go. Got all the gear. and happy to go starkers if nobody around with my shlong flapping around from left to right as I cast my lines when fishing... Oh Joy

Anyhow, before Bow whips me over the foreskin with a wet spaghetti (again) for creating confusion, this game is is date or hate, but before I go there....

GEOMAGNETIC REVERSAL (from wiki)
A geomagnetic reversal is a change in the Earth's magnetic field such that the positions of magnetic north and magnetic south are interchanged. ]

The Earth's field has alternated between periods of normal polarity, in which the direction of the field was the same as the present direction, and reverse polarity, in which the field was the opposite.

These periods are called chrons. The time spans of chrons are randomly distributed with most being between 0.1 and 1 million years[citation needed] with an average of 450,000 years. Most reversals are estimated to take between 1,000 and 10,000 years. The latest one, the Brunhes–Matuyama reversal, occurred 780,000 years ago.

However, a study published in 2012 by a group from the German Research Center for Geo-sciences suggests that a brief complete reversal occurred only 41,000 years ago during the last glacial period.

The reversal lasted only about 440 years with the actual change of polarity lasting around 250 years.

During this change the strength of the magnetic field dropped to 5% of its present strength.[1] Brief disruptions that do not result in reversal are called geomagnetic excursions.

So then, who the heck says N is UP and S is down?

I live in the most uppity part of the world!

Nothing I haven't read already (skipping the highly doubtful reliability of wiki info)

the direction of the magnetic field tells you which is north and which is south...by standarized nomeclature north is the pole that generates the lines (currently this is close to the geographical south pole) and south is the pole that "receives" the lines (currently close to the geographical north)...in couple hundred years, sure it will be reversed...and the back....but for the time being north is the magnetic south and south is the magnetic north...
