Maybe there's nothing you can do to help her; maybe each of us has to learn these hard lessons exclusively through painful personal experience. That's my guess. I'll still do what I can to warn her if she starts to show signs. I think my brother, who is very high-achieving and generally mortified by my illness, is very anxious that his daughter will start to cycle in her late teens. Maybe we'll have more effective treatments by then, which is what my relatives said as they died from cancers, generation after generation.
