all the way down to 120 years (which God capped as the maximum age...whether that is an absolute or an average, I do not know).

It is neither. The average life span is less than 100 years and the maximum is greater than 120! Your bible must be in error.

[GodGunsGuts]

I said maximum. And from what I have heard, the absolute maximum is right around 120 years, whereas the average keeps going up with improved living standards. Whatever the maximum has to do with, it is remarkable that God picked a 120 year maximum thousands of years ago, during a time when the Evos assume that our life expectancy was much, much lower.
