Okay, this thread is probably a litle odd since I'm not asking aobut myself but asking about my grandmother who died 30 years ago, just out of curiosity. Anyway, Mom told me that my grandmother had many weird medical conditions. For example, she couldn't sweat, which could be problematic in summers. I don't know if she had it all her life or if it was congential. (Mom and I didn't inherit this, thank God.) I was wondering if it was part of some syndrome or something, and how common it was. I had looked it up on the Web but didn't see anything that fit -- anything that I found was usually too serious (Grandmom lived until her 60's) or usually found in boys only.
If it helps any, there were 2 other factors that might be related or not. When Grandmom was very young, she had some digestive problem that wasn't diagnosed clearly, but it might have something to do with bile ducts. Whatever the reason was, she couldn't eat anything that was deep-fried or very greasy most of her life. Another weird factor, probably not related, was that she couldn't wear wristwatches -- they'd just stop. She had to use other kinds of watches, like a watch pin.
