Modern medicine is figuring out how to slow the dying process, reducing the cell damage, giving more time for restarting the heart, but they are not reversing dead cells and bringing life back.
My sister went into cardiac arrest 3 times.The first 2 times she was in the hospital when it happened and had no brain damage.The third time she was home with her husband.This was 3 years later.The rescue squad got there 20 minutes later and started her heart beating.I saw her that night and we were told she was brain dead.The doctor said it was too long and they should not have brought her back.Father prayed and we said goodbye and she went to God.That was last Aug.
