The arts and aesthetics offer emotional connection to the full range of human experience. "The arts can be more than just sugar on the tongue," Anjan Chatterjee, a professor at the University of Pennsylvania, says. "In art, when there's something challenging, which can also be uncomfortable, this discomfort, if we're willing to engage with it, offers the possibility of some change, some transformation. That can also be a powerful aesthetic experience." The arts, in this way, become vehicles to contend with ideas and concepts that are difficult and uncomfortable otherwise. When Picasso painted his masterpiece Guernica in 1937, he captured the heartbreaking and cruel nature of war, and offered the world a way to consider the universal suffering caused by the Spanish Civil War. When Lorraine Hansberry wrote her play A Raisin in the Sun, she gave us a powerful story of people struggling with racism, discrimination, and the pursuit of the American dream while also offering a touching portrait of family life.

Sylvan Goldman invented the shopping cart and introduced it in his stores in 1937. It was an excellent device that would make it easy for shoppers to buy as much as they wanted without getting tired or seeking others' help. But Goldman discovered that in spite of his repeated advertisements and explanations, he could not persuade his shoppers to use the wheeled carts. Men were reluctant because they thought they would appear weak if they pushed such carts instead of carrying their shopping. Women wouldn't touch them because the carts reminded them of baby carriages. It was only a few elderly shoppers who used them. That made the carts even less attractive to the majority of the shoppers. Then Goldman hit upon an idea. He hired several models, men and women, of different ages and asked them to wheel the carts in the store and shop. A young woman employee standing near the entrance told the regular shoppers, ‘Look, everyone is using the carts. Why don't you?' That was the turning point. A few shills disguised as regular shoppers easily accomplished what logic, explanations, and advertisements failed to do. Within a few weeks shoppers readily accepted those carts.

In response to human-like care robots, critics might charge that human-robot interactions create moral hazards for dementia patients. Even if deception is sometimes allowed when it serves worthy goals, should it be allowed for vulnerable users? Just as children on the autism spectrum with robot companions might be easily fooled into thinking of robots as friends, older adults with cognitive deficits might be. According to Alexis Elder, a professor at UMD, robots are false friends, inferior to true friendship. Reasoning along similar lines, John Sullins, a professor at Sonoma State University, holds that robots should "remain iconic or cartoonish so that they are easily distinguished as synthetic even by unsophisticated users." At least then no one is fooled. Making robots clearly fake also avoids the so-called "uncanny valley," where robots are perceived as scary because they so closely resemble us, but not quite. Other critics of robot deception argue that when care recipients are deceived into thinking that robots care, this crosses a line and violates human dignity.

Lectins are large proteins that serve as a crucial weapon that plants use to defend themselves. The lectins in most plants bind to carbohydrates as we consume the plant. They also bind to sugar molecules found in the gut, in the brain, between nerve endings, in joints and in all bodily fluids. According to Dr. Steven Gundry, these sticky proteins can interrupt messaging between cells and cause toxic and inflammatory reactions. Brain fog is just one result of lectins interrupting communication between nerves. An upset stomach is another common symptom of lectin overload. Dr. Gundry lists a wide range of other health problems including aching joints, dementia, headaches and infertility that have been resolved in his patients once they eliminated lectins from their diets. Dr. Paul Saladino writes that the hypothesis that lectins are involved in Parkinson's disease is also gaining support, with animal studies showing that ‘lectins, once eaten, may be damaging the gut and travelling to the brain, where they appear to be toxic to dopaminergic neurons'.
