Orcas eat great white sharks. They hunt seals, dolphins, and baby whales. They have never killed a single human in the open ocean. Not once, in all of recorded history.
An orca's brain weighs up to 15 pounds. Yours weighs about 3. They have roughly double the brain cells we do in the regions that handle complex thought. A neuroscientist at Emory named Lori Marino put an orca brain in an MRI and found these animals can tell different species apart underwater. They do it by sending out clicks that bounce off everything around them and come back as a kind of 3D sound map (this is called echolocation). From 500 feet away, an orca knows you're a human and not a seal. It skips you on purpose.
The answer is culture. Orcas around the world are divided into at least 10 separate populations, each with its own food rules, its own language, and its own way of hunting. All of it learned from their mothers. One population eats only fish. Another eats only marine mammals like seals and sea lions. These two populations can live in the exact same water and never swap a single meal. A baby orca learns what food is from its mother, and that list stays the same for life.
In the Pacific Northwest, one population called the Southern Residents eats almost nothing but Chinook salmon. Scientists have documented them killing harbor porpoises 78 times over six decades, carrying the dead porpoises in their mouths, and never once eating them. Even when the group was starving. A 2023 study in Marine Mammal Science looked at all 78 cases and concluded it was play. These orcas would rather go hungry than eat something their culture says isn't food.
Researchers studying whale behavior in 2001 found that orca cultural traditions "appear to have no parallel outside humans." Each family group has its own dialect, its own version of the language. Calves spend about two years just learning how to make all the sounds their family uses. Mothers will slow down a hunt on purpose so their young can watch.
In 2005, a 12-year-old kid was swimming in Helm Bay, Alaska when an orca came at him full speed. At the very last second, the orca seemed to realize it was charging a human. It bent its entire body in half and turned back to open water. In captivity, it goes differently. SeaWorld's Tilikum killed three people during his life in a concrete tank. Research from 2016, published in the journal Animals, traced it to psychological collapse from being locked away from the family bonds orcas need to stay stable.
I think calling this a "mystery" undersells the science. Orcas decide what to eat based on culture, not instinct. No orca mother has ever taught her calf to hunt humans, so no orca hunts humans. Only about 75 of those salmon-eating Southern Residents are still alive. Their pregnancy failure rate is 69% because we've destroyed their salmon runs. They won't break their food culture to survive. Whether we care enough to protect theirs is the part that actually matters.
My favorite part of resurrection is when they went back and didn’t find Jesus where they left him!! Don’t let NOBODY find you where they left you. Elevate! He got up! You can too! Nothing is too hard for my God!
your body runs on an internal clock (circadian rhythm) meaning your body has a 24 hr biological clock controlled by the brain (the hypothalamus)... it controls body temperature, hormones, immune system activity, hunger, mood and even alertness
so at night , this system switches into recovery + low alert mode and that changes how everything feels.
why sickness feels worse at night is because of lower cortisol at night, cortisol is a hormone that reduces inflammation and pain. high in the morning and very low at night
so at night, pain feels stronger, fever feels worse, coughing increases, asthma attacks are more common... the sickness isn’t worse, the body’s anti-inflammatory system is weaker.
there are also several reasons why many deaths happen at night; the body is in maintenance mode, heart rate slows, blood pressure drops and brain alertness drops... so if someone is very sick, the body has less reserve power to fight failure
why you feel more hungry at midnight or at night is because leptin (fullness hormone) drops, ghrelin (hunger hormone) rises, blood sugar tends to dip, brain craves fast energy (sugar/carbs)... also your brain is tired, so willpower is weaker and cravings feel stronger.
the raeson why depression and dark thoughts hit at night, this is BIG... at night there is no noise, no tasks, no social interaction so your mind turns inward and ruminates.
brain chemistry changes, serotonin drops at night, melatonin rises (makes you sleepy but emotionally sensitive), dopamine (motivation) is lower... the brain becomes more reflective, emotional and vulnerable.
there’s also an evolutionary reason that humans evolved to be alert to danger at night, so the brain naturally scans for threats and negative possibilities.
why everything feels more intense at night (general effect) at night: less sensory input > brain amplifies internal sensations, body is tired > pain and emotions feel stronger, logical thinking decreases > emotional thinking increases... this is why breakups feel worse at night, anxiety spikes at night, memories hit harder at night, overthinking peaks at night
there’s also a psychological illusion, when it’s quiet and dark, your brain has nothing external to focus on, so pain feels louder, hunger feels louder, thoughts feel louder, loneliness feels louder... the night acts like an emotional amplifier.
a fun fact, crazy but true, doctors and psychologists say: never make big life decisions at night because your brain is chemically more pessimistic and emotionally biased after dark
learn something. 👍
Yup. And the leader in the middle is Robert F Williams. A Marine Corps veteran who changed the course of the civil rights movement and made an international impact beyond what even MLK Jr. did. But he’s erased from history because they don’t want us knowing that violence can work
At a car meetup in Los Angeles, a group of people began pouring buckets of water through the sunroof of a silver sedan stuck in traffic. When the driver finally stepped out, clearly angry, the guy responsible suddenly looked terrified, and what started as a reckless prank quickly turned into an uncomfortable standoff.
