Oh, sorry to be so thickheaded. This is what I'd read over in the other thread:

John was admitted to the hospital on Friday as a
precaution, as his health is very fragile, not to mention
his older sister Louise just passed away on April 4 as
well, so this is a very trying time for all concerned. He
was sedated so that he would have the strength to help his
family make tough decisions that are to follow.
