If you've ever been to the doctor's office for a checkup, I'm going to assume that there has been at least one point where the nurse has abandoned you for twenty minutes or so while you waited for the doctor. I'm also going to assume that, as you sat there on the crinkly paper on the examination table with silence pressing awkwardly down on you (doctor's office silences are always awkward, even when you're alone) that you became bored and started to scan your sparse surroundings for something entertaining. In my experience, this is generally when one stats to encounter the posters.
Now, usually these posters contain benign things like the pain scale (which I am not going to comment on because it has already been covered by much better bloggers,) the ingredients of cigarettes, and statistics for what demographic is most likely to have which horrible disease, but every once in a while there will be one that makes me tilt my head. See, apparently some of the folks who make posters for doctor's offices thought it would be a great idea to show comparison photos between normal organs and diseased ones. The problem word here is "photos". If you have to question why, here is an example of one that is similar to the one in my doctor's office:
I don't know about you, but I don't want any of these things in my body...
The problem with using actual pictures to show comparisons like this is that everything inside the human body looks awful and disgusting and diseased, and to the non-medically trained eye, it all looks horrible. This is why you use illustrations, otherwise your point is not very effectively made.
I know you're trying to help, medical poster making folks, but... I'm gonna say maybe go back and try again. We don't need don't really need any more reasons to throw up when we're visiting the doctor. Thanks.
