Rubin looks sickly on TV. Very thin and gaunt. Not a good sign at his age.
I saw a recent press blurb that talked about Rubin's lunch at a classy restaurant - a salad and bottled water. Their subtle point was that he was so very wealthy, but not guy into power lunches.
Maybe he's trying to lose weight so he'll get the 'sympathy' factor when he testifies before the many House, Senate, SEC and Justice Department inquiries. He can then invoke victim status!
