Not sure that makes sense. She potentially experiences 12 years of increased stress compared to her peers. I'm not implying that later in life, she will have better tools for work, but that her body would have spent most of her formative years under more stress.

This would then reflect in a shorter lifespan.

Note however that this concept she would gain the tools for hard working in itself is flawed. Studies have shown that those born in the Summer months have statistically lower exam scores.

If stress from school caused people to die earlier I think we'd know by now.

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.

How would we know? Why?
