I played sports as a kid, and always had to start my school year with a doctor’s physical exam. Apparently that doesn’t happen much anymore.
Doctors are physically examining their patients less and less, and relying more on technology. Some doctors are bucking this trend and trying to revitalize the practice of listening and actually touching their patients.
As a woman, I am still poked and prodded on a semi-regular basis (yuck!), but I’ve never had to go in for something serious, and I’ve heard others complain about this phenomenon. I’m interested what the experience of others has been.
For centuries, doctors diagnosed illness using their own senses, by poking, prodding, looking, listening. From these observations, a skilled doctor can make amazingly accurate inferences about what ails the patient.
Technology has changed that. “We’re now often doing expensive tests, where in the past a physical exam would have given you the same information,” says Jason Wasfy, a cardiologist-in-training at Massachusetts General Hospital in Boston.
As a result, many doctors are abbreviating the time-honored physical exam — or even skipping it altogether.

Jonah Lehrer, mastermind behind Front Cortex, has “always been fascinated by tip-of-the-tongue moments. It’s estimated that, on average, people have a tip-of-the-tongue moment at least once a week. Perhaps it occurs when you run into an old acquaintance whose name you can’t remember, although you know that it begins with the letter “J.” Or perhaps you struggle to recall the title of a recent movie, even though you can describe the plot in perfect detail.
What’s interesting about this mental hiccup is that, even though the mind can’t remember the information, it’s convinced that it knows it, which is why we devote so many mental resources to trying to recover the missing word. (This is a universal experience: The vast majority of languages, from Afrikaans to Hindi to Arabic, even rely on tongue metaphors to describe the tip-of-the-tongue moment.) But here’s the mystery: If we’ve forgotten a person’s name, then why are we so convinced that we remember it? What does it mean to know something without being able to access it?
The larger question is how the mind decides what to think about. After all, if we really don’t know the name – it’s nowhere inside our head – then it’s a waste of time trying to find it. This is where metacognition, or thinking about thinking, comes in handy. At any given moment, we automatically monitor the flux of thoughts, emotions and errata flowing in the stream of consciousness. As a result, when a name goes missing we immediately analyze the likelihood of being able to remember it. Do we know the first letter of the name? Can we remember other facts about the person? Are we able to remember the first names of other acquaintances from high school? Based on the answer to these questions, we can then make an informed guess about whether or not it’s worth trying to retrieve the misplaced memory.
Interestingly, a new experiment with a variety of primates (gorillas, chimpanzees, bonobos and orangutans) demonstrated that great apes also demonstrate some rudimentary metacognitive skills. The study, conducted by Josep Call at the Max Planck Institute for Evolutionary Anthropology, involved presenting the primates with two hollow tubes. One of the tubes came with a food reward, while the other was empty. The apes were then observed as they searched for the reward.

From New York Times:
Researchers at the University of Aberdeen found that when people were asked to engage in a bit of mental time travel, and to recall past events or imagine future ones, participants’ bodies subliminally acted out the metaphors embedded in how we commonly conceptualized the flow of time.
As they thought about years gone by, participants leaned slightly backward, while in fantasizing about the future, they listed to the fore. The deviations were not exactly Tower of Pisa leanings, amounting to some two or three millimeters’ shift one way or the other. Nevertheless, the directionality was clear and consistent.
“When we talk about time, we often use spatial metaphors like ‘I’m looking forward to seeing you’ or ‘I’m reflecting back on the past,’ ” said Lynden K. Miles, who conducted the study with his colleagues Louise K. Nind and C. Neil Macrae. “It was pleasing to us that we could take an abstract concept such as time and show that it was manifested in body movements.”
The new study, published in January in the journal Psychological Science, is part of the immensely popular field called embodied cognition, the idea that the brain is not the only part of us with a mind of its own.
“How we process information is related not just to our brains but to our entire body,” said Nils B. Jostmann of the University of Amsterdam. “We use every system available to us to come to a conclusion and make sense of what’s going on.”
Research in embodied cognition has revealed that the body takes language to heart and can be awfully literal-minded.
