I read that Dame Jenni Murray was dazzled by headlights, crashed but was able to climb out of her car. She went into hospital, contracted Broncopneumonia and passed away.
Having recently lost a friend who fell in the road, broke a limb, recovered well in hospital, was ready to come home, then caught Broncopneumonia and passed away, I decided to Google why people catch Broncopneumonia in hospital and the answer states due to low immune system and from other people, staff, visitors etc. The Broncopneumonia viralent in hospitals is stronger than the normal one. I guess I'm wondering why this is happening to older people so often. My friend was planning to come home, we were discussing aftercare and she was a bright, tough 89 year old, she told me she was getting a cold.
