That's right, compare forced marches and limited calories to sporting events.
I played a number of sports, very physical sports, as did my kids and now my grandson. Soccer, double-headers, football, in 100^ weather and I don't recall one instance of a kid falling over and puking.
Speaking strictly for myself, there may be some useful things taught, like the bow drill exercise which I particularly liked, but... the point is that the means don't justify the ends. It is not rational or reasonable to put kids in harm's way for the few useful things they might learn in the process.
If it's emotional breakdowns/throughs you're looking for, I get the feeling that could'be been accomplished at home if the parents had required them to take out the trash or make any other reasonable contribution to the household.
Perhaps the best that could come from this series is that some parents wake up and realize that they are contributing to the disability of their minor.
