This is a hard question for me because I feel like some diseases/ailments can be mixed blessings at times. I've seen people transform their entire lives and credit cancer as their inspiration.

I mean, I personally want to avoid cancer, and I hate that it took my grandma's life. But others have made peace with cancer and even see it as a positive thing. I don't want to take that away from them.

Sometimes I hate my post concussion syndrome, but I also feel like it saved my life. I've made so many positive changes that I might not have made without my concussion history. Then again, who knows.

I think I'd get rid of dementia if I could eliminate any medical issue. It's heartbreaking when your loved ones don't remember their past anymore.
