The message from Cambridge is promising, but Addenbrooke is keeping it shush!
LONDON – The family of physicist Stephen Hawking expects him to recover fully from a chest infection that has left him hospitalized,Cambridge University said Tuesday.
Hawking "was being kept in observation" at Addenbrooke's hospital after being admitted Monday.
"He is comfortable and his family is looking forward to him making a full recovery," the university said in a statement.
It was not immediately clear whether the scientist's condition had actually improved or whether the family was merely basing its remarks on hopes for his improvement.
The hospital declined to comment, referring all calls to the university.
