"You have 6 months..."

How do people feel who are given the number of days or months they are expected to live? I bet for many their whole life perspective changes - how they view life, their interactions, etc. When they walk down the street (if they're able), do they think "nobody knows"...? Is life often put into perspective...an eternal perspective (for believers)? Is it scary? Do they worry about the unknown, about those they'll leave behind?

Life...it's so short. I wonder, though if being told you have a terminal illness can be a blessing in some ways. If the person has a loving family, it might lead to the strengthening of family ties. It might cause the person to reflect more upon God and things eternal, on what matters...
