I think I started getting mentally involved in medical things mainly because of images I saw when young in one of my grandfather's self-help books. It was a publication from 1914 called 'the Pocket Doctor'. And if that is not vintage then I don't know what is ... ha ha.
Later, in the 1990's I found dozens and dozens of old medical textbooks in secondhand book stores. The books were from anywhere between the 1880's and the 1930's - at least those I bought - and contained many illustrations and photos of interesting practices and procedures. They were specialist publications and I surmised they must have been found in the estates of recently deceased specialist practitioners. Of no value to whoever inherited them, these kind of books are often toted wholesale to a junk dealer or secondhand book dealer. I picked them up for a song.
Anyway, the images and photos are of medical offices and settings from those periods themselves and so clearly influenced my mental imagery and preferences. There's also the vague, residual memories of going to doctor's offices in the late 1950's which were equipped in more or less the same manner - with lots of shiny metal instruments, metal and glass cabinets, white tiles on the walls, bright lamps on metal holders, large desks and often libraries filled with leather bound books - much like those I found myself later ...
All of this became intertwined in my imagination - old fashioned, vintage, retro settings and medical fetishistic scenarios ... Sometimes it is so prevalent in my mind, that when I see the latest kind of medical furniture or futuristic looking gyn chair designs, they become something of a turn-off even. There is no longer any sense of apprehension and medical remoteness that I associate with old time medical settings.
I've lots of old instruments, found at flea markets or junk shops and they too add to the whole feeling of those days long gone.
I've seen lots of ads and photos of sites, professional and amateur, that cater to people looking for a medfet experience, but still haven't seen one that really goes the whole way into the retro, vintage felling. That would really be something - feel lie you've stepped back to 1920-1930 and have a medical exam with an emphasis on our medfet proclivities ... I don't think I'd be able to resist having such an experience.
