This is very hard to measure as you would be looking at teaching practices in the 1920-1940s to determine the effects on life expectancy. I think potentially, nationally, this would be possible as most nations have been quite consistent on their school starting times. I do think having a breakdown by month, not just quarter could be even more insightful. |
