Okay, let me explain,
My Grandma has Huntingtons disease, there is a 50% chance i will get it, I am going to get the blood test done soon to see if i am a carrier.
This disease is a dominant gene, if i am a carrier, i will get it, no two ways about it.
I have seen my grandma, lose physical abilities, and her speach is slurred, she has to take at least 10 pills a day, is in a wheelchair, has a stairlift, and bath lift, and needs help getting dresses, having her toe nails cut etc etc. Simple things, that if i couldn't do my self would really upset me.
She is just about mentally with us, eventually she will lose this. Having seen her, i dont want to be the same. I want to be able to sign a letter, saying i want things to end in a medical way when i lose my mental abilities.
Just my choice x
