Since having a medical education, it has made me look at people in ways that I never used to look at them. I’m more observant of people around me.
In medical school, the crucial thing we were taught, was to use our eyes. In our clinical examination classes, we were taught that a general order of examination of the patient was: observation, palpation, percussion, auscultation. Note how observation comes first and foremost before you touch them, and before you use your stethoscope.
And so we’re told that you can glimpse a lot of information about your patient just from watching them. A person who limps into your practice may indicate something like pain from the knee or hip (maybe from osteoarthritis), and an infant who is brought in in the mother’s arms with reduced responsiveness and alertness is probably quite sick.
When you’re observing people all the time, it only becomes natural that you apply it in public. In general, the major thing I glean from seeing people are whether they are well or sick. Then little other subtle things I may observe – things like gait, scars present (may indicate things like past knee replacements), and just other things in general like if they’re pale, have rashes or so.
In turn, I guess being able to apply it in public means that I’m constantly using the skill of observation, and hopefully it will aid in my further career development.
