.50 cal sniper rifles and shoulder launched weapons like Carl Gustaf, the M72 LAW or the AT4 can. Firing a rifle may or may not cause shock waves that are strong enough. If you have been firing a whole day you definitely feel funny in the head.

that feeling might be partly due to the large amounts of lead compounds in primers being inhaled by the shooter

They still want to have sex with sexy people, and many people, when they're in the mood to have sex with sexy people, don't want to use protection. And some of those people who were not in the mood for protection also don't have access to abortions, and some others actually want to raise children by themselves for some reason. This is the actual process of human natural selection, and it's not much influenced by laws…

> and many people, when they're in the mood to have sex with sexy people, don't want to use protection. I don't believe not using a condom with a Tinder date is an option, at least in the West. No matter how attractive and insisting the male is, a woman knows she is the one to bear the consequences. Even if they're on a pill, STDs are still a thing, so why take the risk.

> a woman knows she is the one to bear the consequences

The man has to also bear the consequences in most nations, since he has to pay a lot of money. They like sex, but not at that price.

Lead poisoning symptoms take weeks to months to emerge. It would show in a blood sample.

Rifles would never do this. They probably usually/always wore ear protection during training. Even if not it wouldn't do it. Many civilians fire guns throughout their lives, often without ear protection. This would take a much bigger explosion.

If you have been firing a whole day, you definitely fell funny in the head. Ear protecting does not protect brain much. It protects hearing. Brain heals from very mild damage when there is time to rest, but when you shoot all day, day after day, the damage can accumulate. One already recognized problem area is the show wave getting between helmet and skull. It can amplify the impact. Nobody knows what the impact from…

People that hunt and shoot guns their whole lives do not commit suicide at high levels. This is what I am basing my statements on. Basically half the people I know in the US fall in to this category.

FYI, also modern helmets are not designed to stop bullets but rather to protect from shrapnel and hand grenades. Stopping a bullet would mean breaking the wearers neck. (The kinetic energy needs to go somewhere after all.)

I don't think it would break the neck. Typical AK47 bullet at 100yd has momentum 5 kgm/s, which is about the same as a baseball at 77mph.

My favourite bit of AK47-helmet interface knowledge is that a French Jaguar pilot took an AK47 round to the helmet in the Gulf War. While flying.

(He survived, it's not really relevant here as it didn't stop the bullet - there was an exit hole too).

Men in the special forces shoot firearms much, much more than even enthusiastic hunters. Thousands of rifle rounds in a day. All day long.

A hunter (I am one) might shoot a dozen rounds to zero in a rifle, or a hundred shells at a clay range. Actually hunting is never more than a handful of rifle rounds or a few dozen shells.

It indeed can't be too big because the shooter takes the same or greater momentum in the form of recoil. Conservation of momentum applies to the process of accelerating the bullet.

Pressure buildup in the cranium due to microwave heating? Victims have reported a feeling as if their heads are about to explode.

Huh. I feel like that almost daily nowadays. Maybe I should grab some tinfoil. Unless it's coming from inside the head...

Go see a doctor. Run. Don't walk.

Why on earth would you think laws would be necessary? This mechanism is older than laws or human civilization itself.

Because in practically every country there are laws on marriage, and it's usually (Muslim world being the exception) 1:1 in partners. It adds legal and financial protections for both parts of the couple. Unless there's a law change, how do you see this working? A married man going around spreading seed and women getting pregnant and going at it alone?

Why do you think the sexual revolution happened right on the heels of WW2?
