Look into it. The guy was just steps away from being a ghost today. Is he really senile enough to be at these events without a little CGI magic help between naps. The last few months have been more than bizarre.
You are implying someone is mentally ill which I believe is against HN's rules, and in any case is a failure on your part. Watch the video before making immature comments, then decide:
I'm not saying they are mentally ill. I'm saying they seem disturbed, and would probably benefit from some kind of counseling and staying away from Internet discussions and politics.
