Having lost my 23yr old sister to SADS i know how quickly it all happens and nearly 4 yrs on i still think of her every day. To me from the blog it was just something thats happened scarily quickly, all i can hope is that if it was SADS that if she wasn't an only child her parents had the other kids screened to prevent a possible re occurrence. Yet again another touching but informative post - thank you for sharing .
