Let alone pass the airport test to get any where at work.
I'd recommend reading the article, it's interesting.
It's really rather a shame that there is very little we can glean about the social customs of our prehistoric ancestors in this regard.
brb, i'm gonna go work on my time machine.
But if you live in a society where it is fairly normal for mothers to die giving birth, or for children or friends to die or be maimed for life (and where it must have been fairly common to see corporal punishment of slaves) seeing healthy men die suddenly in horrible ways may have had a smaller effect than it does today.
But of course, outside the battle field, they had it way worse than present-day soldiers (at least those for rich countries such as the USA). No antibiotics, no rescue helicopters, no air-conditioned hospitals, etc. That may well have compensated for that.
The Battle of Gettysburg saw over 4000 dead on each side in a 3 day period. That means, in 3 days, more US soldiers died than in 13 years of the Afghanistan and Iraq wars.
It's estimated that the Normandy landings on D-Day had 14,000-19,000 casualties total (all sides).
The Battle of Antietam had 22,000 casualties in a single day. Cold Harbor may have had up to 7,000 in a matter of minutes.
At Gettysburg, Pickett's division suffered around 60% casualties in their one charge, including a 100% casualty rate among regimental and brigade commanders, prompting his famous comment to Lee (on being told to prepare his division for a possible Union counterattack) "General Lee, I have no division".
It was a relentlessly and almost unbelievably bloody conflict, and yet both sides found the will to keep it going for four years. What sticks out to me is Grant's comment after the first day at Shiloh (which had been close to a massacre of the Union forces) in response to Sherman, who said to him "Well, Grant, we've had the Devil's own day, haven't we?" Grant simply said "Yes. Lick 'em tomorrow, though."
And he did. In the end it was that stubbornness and willingness to keep pressing on in spite of the horrific casualties that won the war.
