I wish Billy all the very best, and as Wellfield has said Michael J. Fox has had Parkinsons since he was in his late 20s or early 30s and he's still on the go. There's a huge difference in their ages of course, and it's different with everyone, so all we can do is wish him the best on both conditions, goes to show that none of us are immune to such things.
Good Luck Billy.
