Just received this email from David's wife Maureen:
Hi Mike and Rosey,David collapsed in the middle of the night last night and fractured two ribs and also put couple of lumps on his head. He is (in the hospital).They are taking tests, and will keep him for a couple of days.Maureen
David has been struggling with pneumonia but was getting better. This is a real setback and so keep him and his family in your prayers.
LATER: Spoke briefly with David who, in great pain (think pneumonic coughing with two broken ribs), confirms the above and asks politely, "Tell everyone to leave me the hell alone, okay?" I don't think that request prevents prayers offered in his behalf.
