I also find myself looking at people walking down the street and I picture them dead on the autopsy table... not very pleasant.
Well, I do not picture live people on the table...BUT, for many many years to present time, I envision what people look like on the inside based on what is on the outside. Fatty livers, large hearts, athero...
My mom particularly finds this to be a very nerve-wracking habit, telling me to "cut that out" if I even glance at someone for unrelated reasons.
Another factoid is that while I do all of my own evisceration (minus sawing the head & stripping dura), I am very selective about when I run bowel. Since we eviscerate organ by organ, my method of removing the bowel is to transect at ligament of treitz and with a scalpel separate the mesentery from the bowel, leaving the small & large intestines attached, then dissect rectum low in pelvis. I then "peak" at certain parts of the bowel, including opening up the duodenum in situ, and a few cuts along the length of the gut. I then run my hand along the entire length to avoid missing any masses (or condoms filled with drugs!) I know that I miss small polyps, but I can live with that. If no masses and no blood in the lumen, I do not run the bowel.
I became a six-year no-red-meat-eater in med school as well, because of an arterial tree I dissected out of a corn beef brisket! Happily, I am back to eating red meat!
Back to the point, though... As pathgrrl says, there it is simply amazing to be able to see human anatomy and pathology in the way I am able to at an autopsy. It remains mindboggling that (many) others do not feel the same way.
