Graedy's last posts said he'd be in the hospital 7-10 days from the surgery (August 1), so it isn't quite time to panic just yet. His last post said "see you in a couple of weeks" so it might actually be longer than that.
I think we can set the official "time to start worrying, lets send someone to Germany to look for him" date on August 22nd, three weeks from the date of the operation.
No panicking until then.
