Adjustments

For some time post the pole shift the Earth will not have as much "air" covering it. What that indicates is that the barometric pressure at the surface will be less than it is now. Just how much less? That's a very important question. Will the barometric pressure be, say, about that found on the mountain tops? If yes, then we must seriously reconsider our plans for physical activity post pole shift for some unknown time. Why, you ask. Because your ability to perform physical work will be seriously curtailed. You will feel "out of breath" because the partial pressure of the oxygen will be much less and your body unable to get the same amount of oxygen in a breath of air as it is currently accustomed to. Over time, you will adapt to the lower atmospheric pressure as do people who live at very high altitudes. But before you do, you will be in a similar situation as are mountain climbers who have to take bottled oxygen with them in order to maintain their physical activity.

All we know from folk lore is that "the sky was low to the ground" or something along those lines. No one gasping for air. That could be fog also, fog here in San Francisco is as thick as clouds, so maybe that is more moisture in the air, etc.

If the air pressure drop is anything significant, many people will experience headaches until they are accustomed to the pressure drop, usually anywhere from a couple of days to a couple of weeks to get used to it.
