I think there is something to be valued about historical accuracy.

> Like the statistics on plummeting mental health and happiness, an obesity epidemic, increases in "deaths of despair", and plateauing or decreasing life expectancy?

In the 60ties, suicide rates went UP. Peaked around 1970 and we did not reached their levels.

Long terms statistics about alcoholism rates and drug use are also a real exiting thing. We know that cirrhosis death rate was going up in the 60ties up to 70ties, peaked and went down. It was the time when drinking and driving campaigns started.

Current drug use is nowhere near what it was a generation ago.
