Thanks guys.
On a cheerier note due to the fact I've learned so much about it in the last few years, I have learned that preventative treatment perhaps isn't a million miles away. Just too late for some, unfortunately.
Thanks mate. Its horrible to watch how they waste away, he was a shell at the end and you'd have to say it was a relief for my mum in many ways as awful as that is.
You are right about the 5 years though. Was diagnosed around 65, gone at 70.
