Over the years, I've been weighed a number of different ways. I remember for pediatric exams as a child and teenager I was typically weighed in the exam room after I had disrobed. I would be standing on the scale in just my briefs. And as a young adult, it was the same thing, being weighed in the exam room after you were already undressed. I never remember wearing a gown for those early exams, just underwear.
Then as I got a little older, I remember being asked to undress completely (including removal of any underwear) and put on a gown. For those exams I was also weighed in the exam room but wearing only the gown.
Fast forward to the last 10 to 15 years and for most of my exams I was weighed in the hallway on the way to the exam room. Sometimes I'd be instructed to remove my shoes, other times they would simply try to compensate for the shoes along with any clothing I was wearing at the time. Those were all done fully clothed.
My current doctor has exam tables that are capable of weighing you. Now when I arrive for a physical, the nurse has me sit (still fully clothed) on the exam table while she goes over my meds and takes my vitals. She presses a few buttons on the table, it raises up a bit to weigh me, then lowers back down automatically. It's all done with me fully clothed and is obviously just as inaccurate as being weighed in the hallway.
The same nurse comes in and does my EKG a few minutes later, and for that I'm always undressed except for my underwear (usually just a jockstrap). So I'm not sure why she doesn't wait until then and weigh me unclothed. Perhaps next time I'll tell her that I want to check the accuracy of my scale back home and ask that she weigh me unclothed for a more accurate comparison.
And finally, a few years ago I had a "sports physical" at an urgent care place that weighed me in the hallway. The exam form I was using said that my weight was to be recorded undressed or in a gown so that's exactly what they did. The nurse instructed me to undress and put on the gown, then to meet her in the hallway once I was ready. I stripped down to just my jockstrap and put on the paper gown. I remember that I couldn't get the gown to tie correctly, so I ended up just holding it together in the back. And while I was on the scale I moved my hands to my sides letting the back of the gown separate. I'm sure she had a nice view of my bare jockstrapped ass!
The one thing that's missing from my life experiences is being weighed completely nude without underwear or a gown. I can't remember ever having that experience, unless it occurred when I was a very small child. I'd love to experience that today as an adult, but I doubt I ever will.
