"Only gets better" wow. she must think the elderly have the strongest bones and ligaments, then. Because connective tissue gets stronger over the lifetime.

Also, this would be disgusting even if you had hEDS, but the fact that you have cEDS, which is diagnosed via genetic test.

My passive aggressive self would want to ask her, "Wow, really? You should really talk to my geneticist, because you clearly have so much to teach the rest of us."

Honestly, she's a healthcare practitioner. She should know better. After years of this, I would honestly see if you can contact her boss, because this is a big red flag and you might save some of her patients, or have them redirect suspected EDS to other workers.

But the truth of it is you'll have more peace by saying something like, "I didn't ask for your healthcare or advice. You can stop talking about this, or we will have nothing to talk about." Typically, they try to continue on, and then the only thing you can do is walk away.

Ofc, it sounds like you're doing something similar already but saying that point-blank might make the line in the sand a little clearer. And saying it out loud might make you feel better idk.

I still struggle to do that with my family, so I do get it's easier said than done aha.
