A school in Indiana has been criticised for apparently shooting teachers "execution style" with pellets as part of an "active-shooter drill". The case has reignited conversations about the usefulness of drills and the methods used to prepare schools for shootings.
[...] Many experts agree that discussing and practising how to respond to a dangerous situation will help protect students who find themselves faced with the real thing. Fire drills, for example, are well established tools to teach children how to behave in a potentially life-threatening situation.
[...] While more realistic and stressful situations may be appropriate here, he says "large-scale, prolonged, realistic drills are not ideal" for children.
[...] "Children being asked to pose as victims on the floor covered in fake blood is just pointless and can be traumatising, I can't see why that's necessary."

Medical research will improve, but only when we are able to synthesize the necessary organs to do proper medical experiments. Things like the heart cells on a chip for testing toxicity to the heart as an example.
One of the often forgotten legacies of WWII is that we no longer permit doctors to perform the necessary sorts of research to really determine what medical treatments work. We have to do proof via induction and we can't do longitudinal studies in cases where the treatment appears to work because it's unethical to deny effective treatments due in large part to the Tuskegee experiments relating to syphilis.
But yeah, right now a lot of those medical recommendations are based on little or dubious work. Sodium and cholesterol recommendations are largely based on fiction.

I looked into the RDA for magnesium the other day and it was based on very limited data available for a couple dozen people in the 1990s. Further, it was twice as high as a later study indicated.
And all values relied on the dubious assumption that everyone should consume exactly enough so that consumption - excretion = 0.

The need for magnesium varies by person. Something about my past traumas seems to have rewired whatever systems (am guessing the HPA axis and the associated mineralocorticoid regulation pathways) handle my electrolytes, the result being at least 600mg a day as citrate is necessary for optimal function. Sure as hell the soil doesn't have anywhere near as much as it used to...
