Getting my various wires caught on things
Because I have an insulin pump for type 1 diabetes, this means that I constantly have a long loop of plastic tubing connected to my torso at all times.
The insulin pump is a pager-sized device that I carry in my pocket. You can get a little belt holster for it, but frankly, having a pager sized object on my belt at all times caused untold problems for me in middle school (it's so easy to knock it off when you accidentally clip a table or a doorframe!) so I'm never doing that again. The pump goes in my pocket, along with most of the tubing, and the remainder runs up my hip under my shirt and attaches to my insulin pump site, which is usually either on my side, stomach, or thigh.
The pocket strategy is best at preventing your pump from getting clipped off by a doorframe and flying around you like an asteroid, but there's still the problem of the tubing. It can get caught on things. Doorknobs are my enemy.
I have a constant, subconscious awareness of doorknobs, and of the location of my pump and the tubing. I sometimes don't really know what pocket it's in, like, intellectually, but when I pass through a door I will be highly aware of the tubing and the doorknob and will contort myself almost autonomically, if needed, to avoid looping any stray length of tubing around the knob.
A few times this past week I've had reason to walk around my apartment while my pump was detatched - I let it run out of battery and had to charge it briefly while doing other things, which was a huge hassle - and it is so profoundly strange for me to be walking around with empty pockets. When I take a shower, the pump goes back on before I leave the bathroom. So walking around without it is just... alien. I've had a pump attached to my body almost all the time since 6th grade. That was, like, 24 years ago. Being without it feels extremely wrong.
There's currently research going into "smart insulin" in China, which would be a shot you'd take once a week and which would administer itself, somehow, over the course of that week, by slowly losing some polymer coating that would unlock the insulin to act in your body gradually over time. If they can get this to humans eventually, that means there is probably a future moment where I am taking this shit instead of using an insulin pump. If that ever happened to me, I would absolutely be losing my mind from, like, some kind of phantom pump syndrome. I know that without the pump, my mind would be constantly searching for the pager-sized weight in my pocket. Very, very strange to think about!! I'll be dodging doorknobs forever whether I have a reason to or not. I've been doing it for too long to stop, at this point.
