What a tradgedy...

I know very little about Huntingtons and had never heard of it until I started looking at the background to rock music and discovered Woody Guthrie (who influenced Bob Dylan, who in turn influenced people like Elvis and The Beatles.....)

Woody was diagnosed with Huntingtons at 40, and his mother had died with it at 41.

Its a tragic illness, and all the more so for the youth of your niece.

The way I look at life, children choose their parents, and although it may be poor consolation, these two found their ways into your sister-in-law's life - albeit by different means. They will have chosen parents who have the potential to cope with this... I wish them strength.
