Many have said exercise is good
but never has it been explained to me in a convincing manner.

2-Did they die of nutritional deficiency?
While I'm speaking of them,
3-Have any tests been done to estimate the average length of life
after specific nutrients are removed from the diet?
I wonder how long it takes to die from each nutrient deficiency.
4-What phrases could I use for a medline search?

Possibly, but there is generally less O at higher altitudes.
I imagine the red cell count balances the lack of O.

High red cell count also means high nutrient distribution,
provided there is enough fluid in the bloodstream to fill the capillaries.

If there are increased amounts of fluid in the bloodstream
(5- input technical term here: hyperfluidity?)
there are also increases in efficiency of temperature distribution,
preventing hyper/hypothermia, thus leading to decreased free-radical
from sweating/shivering.

6-Do people host more bacteria( which do not like high levels of O)
at high altitudes when they have a lack of white cells to fight them?

I've been wanting to know how low I can get my heart rate
if I increase my red cells and my O saturation.
7-Any predictions?
8-Hmm...any risk?

Hej, Anders. :-)
