Interesting. I'm still trying to figure out St. Bernadette though. Now she was truly a fascinating site. Her corpse is over 130 years old and she still looks exactly as she did the day she died. Her body has yet to decompose!
When Pope John Paul died, my mother told me that they will exhume his body after 2-4 days to see if he has begun composing. If not, he would be declared a saint. This kinda makes me wonder if the Vatican assumes all saints don't decompose.
