Compared to a variety of other chronic conditions, this is a benefit of diabetes -- it is a condition one can treat and live a fairly "normal" life, and therefore be a fully-functional doctor, sharing that experience and expertise.
Much harder, even impossible for some other chronic conditions, like ALS, to pick one that in later stages is completely debilitating.
I was talking to my wife yesterday about how far we've come in diabetes management and treatment in the last 30 years. Really, the improvement for us PWD is enormous, and remarkable. My grandfather was dealing with his D with pee strips and pig insulin, with a weekly (maybe less often, I don't remember) blood check at the doctor. His ability to manage this disease and live a "normal" life was, well, pretty much non-existent. He had all sorts of complications that I'll probably never have to face. His PWD peers were in pretty much the same boat.
By contrast, I can "think like a pancreas" and do something about it. With a CGM and pump, I can rock a 5.9 a1c, and be a diabetes star to my health team. I can eat pretty much what I want (within reason, of course, I'm comparing to grandpa).
Modern diabetes treatment and diagnostics has made living with this disease, well, actual living. It's still an enormous burden compared to not having it, but at least we have so much more control over our own fate now.
For that I am profoundly grateful to the men, women, and companies that have made this possible.
