Aah, but in all that you wrote here you didn't use the word 'better', which was what i was talking about.
Better is an opinion and is not based on hard data.
Better is always from some(ones) point of view.
And i agree with most of the rest of your post, hard facts are hard facts.
Then it's just playing with semantics, and I'm not interested in that.
Now, what's relevant? Hard data suggests some things that we need and some things that we ought to avoid. That's enough to start a scientific discourse about well being.
