Hello, I'm new here and I just have a few questions. I've looked everywhere and for some reason I just cannot find anything. I was wondering if anyone knew what kind of onset, quick or prolonged, and the
duration, long or short, of an/a:

-87 year old who died of natural causes watching TV on her couch,
-47 year old male who died head on in a car accident,
-66 year old woman who died of breast cancer
-12 day old infant,
-457 pound woman 54 years of age
-35 year old male who was in a vegetative coma for 3 years.

In case you are wondering yes this is for school. I'm currently studying to be a Funeral Director in the U.S( not that that means anything just in case anyone was wondering where i'm from). This is an embalming Homework and I've searched all my textbooks and any websites and the library. Which leads me to this forum. I would appreciate if anyone could help me or guide me to where I could find the answers. Thank you in advance.
