I just recently read of protective and beneficial effect for the body of
free radicals. It hasn't been elaborated too much but the conclusion was
that we are wrong fighting it.Another area of confusion for me.

If this is true (and I assume it is) I wonder why they ate so much. I read
that they ate at least 5 times a day huge amounts and meat and fat and
basically were described as 'always hungry' people.

Exactly, but I don't think anybody can answer it. It will be only
speculations like lack of vit C, lack of sunshine, excessve protein,etc.
Plus our medicine (we may critisize it) has many ways to prolong the life
even if it means prolonging the misery.

It is difficult to isolate variables.  In

But still life expectancy is the highest among people living in rather cold
climats.
