British Marine Samuel Giles William Alexander survives a gunshot to the head thanks to his helmet.

Sadly, he would later die in Afghanistan, earning Britons top honor, the Victoria Cross, while valiantly defending his platoon by firing every piece of ammo he could find.  When he ran out of bullets, he picked up the next gun he saw on the ground and continued fighting.  His bravery saved the lives of two of his wounded men. https://www.gov.uk/government/fatalities/lieutenant-oliver-richard-augustin-and-marine-samuel-giles-william-alexander-mc-killed-in-afghanistan

Second premise: Not all children are smart and clever. Got that? Kids are like any other group of people: a few winners, a whole lotta losers. There are a lot of loser kids out there who simply aren’t going anywhere, and you can’t save ‘em all. You can’t save ‘em all, you gotta let ‘em go, you gotta cut ‘em loose. You gotta stop over protecting them, ‘cause you’re makin’ ‘em too soft. Today’s kids are way too soft. For one thing, there’s too much emphasis on safety. Child proof medicine bottles, fireproof pajamas, child restraints, car seats—and helmets! Baseball, bicycle, skateboard helmets. Kids have to wear helmets now  for everything but jerkin’ off. Grownups have taken all the fun out of being a kid just to save a few thousand lives. It’s pathetic.

Roman Iron and Tinned Bronze Calvary Parade Helmet, Second Half of 2nd Century - Early 3rd Century AD

Formed of iron with tinned bronze overlay decoration including a stylized band of laurel around and over the crown, eagle wings on either side, a large eagle with outspread wings standing on a groundline in relief at the back above the neck-guard, flanked by architectural elements consisting of lozenge filled rectangles surmounted by triangles, the neck-guard flaring out horizontally, ear-guards riveted at either side, the ornate cusped cheekpieces with naturalistically-modeled ears, each with a central boss surrounded by scallop shells.

Extremely Rare Bronze Age Horned Helmet, Denmark, 900 BC

This is one of a pair of bronze horned helmets from the younger Bronze Age (c. 900-1100 BC) found in the Brøns Mose swamp just west of Veksø, Denmark during peat digging in 1942.

European Bronze Age and Iron Age horned helmets are known from a number of depictions, but few actual finds. These were probably used for religious or ritual purposes, possibly representing the Alcis, the two divine twins who were worshipped amongst early Germanic peoples. They are first mentioned in Tacitus’ 1st century work Germania, where he writes,

“The Naharvali proudly point out a grove associated with an ancient worship. The presiding priest dresses like a woman; but the deities are said to be the counterpart of our Castor and Pollux. This indicates their character, but their name is the Alcis. There are no images, and nothing to suggest that the cult is of foreign origin; but they are certainly worshiped as young men and as brothers.”
