Intelligence correlates with preference for breasts over buttocks in men globally
African ancestry is linked to a higher preference for buttocks over breasts
Search data from Google and Pornhub show interesting patterns in body preference

Racial disparities exist in lethal injections, with Black individuals being 220% more likely to experience botched executions than white individuals.
Medical myths and implicit bias contribute to unequal healthcare outcomes, but they do not fully explain the racial disparities in lethal injections.
There is an opportunity for the medical community to reflect on racial inequalities and the impacts of medical racism in the context of lethal injections.

Cuckoldry in history is related to natural history and terms like 'horny' stem from old German farming practices.
The concept of 'wearing horns' generated a vocabulary around cuckoldry and male infidelity.
Slang terms for male reproductive organs and impotence reveal societal attitudes about virility and masculinity.

Tycho Brahe's story shows how ignoring the urge to pee can have serious consequences for health, as it may lead to fatal infections. It's a reminder that some bodily needs shouldn't be ignored, even in social settings.
The bladder fills and sends signals to the brain that motivate us to pee. This system is controlled by specialized cells that detect stretching, similar to how we feel full after eating.
We have the ability to control when we pee, which helps us navigate social norms and situations. This skill allows us to prioritize different needs but can sometimes lead to difficult choices.

Not all LLMs are equal in understanding basic human anatomy

Our ancestors were successful in evolution, leading to our existence today. Every single one of us is part of a long line of evolutionary success.
Mammals have evolved unique traits such as mammary glands, four-chambered hearts, and specialized teeth, making them distinct from other species.
The mammalian brain has evolved to be large, well-connected, and specialized, with a balance between autonomy and integration, as shown in the structures like the forebrain and the corpus callosum.

Research suggests it's better for the environment to buy conventionally grown food than grow it yourself.
Shoulders have an interesting origin connected to skeletal evolution.
Author Edith Wharton's work gets a new appreciation over time.

Cholesterol is essential for digestion as it is used to create bile acids, which help digest fats.
Bile acids act as emulsifying agents that mix fats with water in the digestive system, aiding in fat breakdown by water-soluble enzymes.
Bile acids are converted to bile salts, which are more effective at mixing fats with water and are stored in the gall bladder for future use in digestion.

The study of anatomy in Victorian London evolved from grave-robbing to a more regulated system with cadavers sourced from workhouses and teaching hospitals.
Dr. Thomas Cooke's School of Anatomy faced challenges due to its location in a densely populated area causing complaints from neighbors about the unpleasant odors and disturbances from dissecting activities.
Despite facing setbacks, Dr. Cooke was known for his innovative teaching methods and contributions to medical literature, emphasizing practical work in anatomy and advocating for hands-on dissection.

Isoprenes are essential compounds found in every living cell, with various important functions in the human body such as being precursors to cholesterol and coenzyme Q10.
Humans obtain crucial isoprene compounds from their diets, which are not produced by the body, and they are also present in medicinal plants like licorice.
Isoprenes play a vital role in the synthesis of glycoproteins, which are essential for cell communication, and are involved in anchoring proteins to cell membranes for various functions.
