So I just got some fantastic news.
I have a family history, as well as a few of the early warning signs of Parkinsons Disease, however I've just found out they've recently found a way to "fix" it that nobody has ever done before, it still involves brain surgery and having a battery attached to you all the time but by the time it ever effects me properly it should be fixable. So now that's one less thing I have to worry about.
Although family history and warning signs considered, they're no guarantee that I'll ever actually end up with the disease since the warning signs could be from various other things, but it's nice to know that it'll be alright if it does end up being that bad.
