I've done a lot of white water boating but never been pinned, strained or held under on the river. I mostly ran OCs, which are easy to escape from.

Swimming in the ocean, I once got held under to the point of near panic when I was taken by a turbulent rip current. I escaped by sprinting with breathing attempts side-to-side on each stroke and finally got enough velocity to catch some air and stay surfaced. They say to swim parallel to shore in rips, but the water was much too turbulent to do anything but a blind breathless sprint. It was swimming velocity and swiveling my head to find air that saved me that day.

In 2016, a then-87-year-old man was connected to an electroencephalogram, or EEG, when he unexpectedly had a heart attack and died. Researchers later published the results in Frontiers of Aging Neuroscience.

An EEG measures electrical signals that the brain produces in order to help diagnose or examine certain neurological conditions like seizures and memory loss.

Sure enough, doctors were monitoring the man for a series of recent seizures when his heart suddenly stopped beating.

In the paper, researchers reported that during the 15 seconds leading up to the man's heart attack, the EEG scan revealed high-frequency brainwaves called gamma oscillations, which are thought to play a role in creating and retrieving memories.

"It is very hard to make claims with one case… but what we can claim is that we have signals just before death and just after the heart stops like those that happen in the healthy human when they dream or memorize or meditate," lead study author Dr. Ajmal Zemmar told Insider's Anna Medaris.

Of course, these scans are of a man seconds before death and not exactly equivalent to an NDE, where the person survives. However, such activity may help explain why people see memory flashbacks or faces of people they know during an NDE, Greyson said.

Moreover, EEG scans of people attempting to remember their NDE also provide more clues to what an NDE does to the human brain.

When people recall an NDE, the brain "shows increased activity in many different parts," Greyson said, "such as those associated with memory, vision, hearing, and emotion."

In particular, the temporal lobe, which is responsible for helping process sound and encode memories, is thought to be associated with out-of-body experiences and memory flashbacks during NDEs, said Dr. David San Filippo, an associate professor at National Louis University and a near-death experience researcher.

"That has led some people to believe that near-death experiences are simply biological, chemical reactions to the brain dying," San Filippo said.

To that point, a study in rats suggested that the overwhelmingly positive experience people report with NDEs may be linked to a flood of serotonin the brain releases. This may be the brain's way of gradually preparing the body for death by inducing feelings of euphoria and pain relief, San Filippo said.

What do you mean? Don't you always do it standing and start from the stomach?

I should go re-learn Spanish but even some of those watching the video were saying what I believe means "harder" essentially (mas fuerte) so they knew it was off as well. They also drew me to the machete which I initially missed given the main focus.

But I'll give them props for actually responding rather than just standing around and filming.

He obviously didn't wait 30 minutes after eating.

Every parent should show this footage to their kids to show what really happens when you break the 30-minute rule.

No, the guy was actually tripping, I mean he was probably having a psychotic break, and he thought he was fighting with a sword. He actually had a kind of machete and left it by the pool, you can see it taken away by a man at the end of the video, and the people are commenting about this.

the stooge in the black shirt trying to squeeze out the shit?

The other dudes were like **** that, I can’t swim either

There's a reason why you don't see any black swimmers at the Olympics
