I'm trying to recall a quote I read some time ago.
The gist was that ‘Everything we've learned in/about x we learned through blood’, with the implication being that every current rule/practice in x came to be because somebody came to harm in the past and the rule came about to avoid that harm in future.
I can't remember what x was, which is stymieing my attempts to search online, but I believe it was either:
- the military;
- health & safety; or
Can anybody help me to track down this quote?
