People in the northeast of the United States think they have greater "wellness" than everywhere else except California. People in the southern United States think they have more wellness than everywhere else.

Which is right? They both are. Wellness may be in social media ad campaigns and have diets and apps and fads under the umbrella, but it's entirely subjective. The northeast believe they have greater wealth and social standing, which they consider traditional wellness. The south sense of purpose and community identity, which is existential wellness.

If you have spent any time on social media, you have a different kind of bystander effect in action. Psychologists say if many people are around, the bystander effect is why everyone is less likely to help. They believe someone else will be more competent or know something you don't. If you walk by a person laying unconscious in New York City, based on experience they did not have a heart attack and are in peril. They are on drugs or alcohol.

Colors trigger unique brain responses, the subjective nature of our brains and eyes, not to mention different media, is why a famous blue dress experiment took countries by storm.

To try and help determine how different people have the same brain responses to colors, researchers measured color-induced brain responses from one set of participants. Next, they predicted what colors other participants were observing by comparing each individual’s visual cortex brain activity to color-induced responses of the first set of observers. 

One key hallmark of being human is walking on two legs. It was a seismic shift seen in no other primates. Like much of evolution, it happened in fits and starts. The 4.4 million year-old Ardipithecus of Ethiopia was a tree climber with a grasping toe that would walk upright 3.2 million year old Lucy had a pelvis brought upright walking closer, with flaring hip blades for bipedal muscles.

Some of that legacy remains in our closest relatives, the African apee, e.g. chimpanzees, bonobos, and gorillas, have upper hipbones (ilia) that are tall, narrow, and oriented flat front to back which anchor large muscles for climbing.

Some sixty million years ago a fountain of hot rock that rises from Earth’s core-mantle boundary unleashed volcanic activity across a vast area of the North Atlantic, from Scotland to Greenland. We can detect the effects in spectacular basalt columns of the Giant’s Causeway in Ireland.

But why Iceland’s fiery mantle plume had such a dramatic impact has been the subject of debate.

Advanced cancer often brings preparation for the worst and proponents of the modern health care system use terms like "advocate" and "empowered" when everyone who isn't part of the system knows patients have trouble doing the former and certainly are not the latter.

Government, health insurers, and hospitals make the real decisions, and even if that goes your way doctors may do what they want. That is why nearly 40% say their wishes are ignored when it comes to their care goals.
