Most statistics can be skewed to serve many purposes. Add to the above the facts that between 1900 and 1945 the average human lifespan in the western world was 52 years. By 1950 it had gone up to 70. Now in the 3rd Millenium we can expect with some confidence to live into our 80's. What conclusion do we draw from this?

I think we would be skating on pretty thin ice if we deduce that some event at the end of WW2 increased our life expectancy significantly. In much the same way it is very unsafe to conclude that the same event triggered an increase in anything!

What you make of it is entirely up to yourselves. Me? I can only conclude that studies, particulary expert studies, have a way of counter-acting each other.

Believe nothing you hear and only about half of what you see!
