There's some disagreement in the medical community regarding CPR.
The majority don't think it should be done, at all, in most circumstances.
Young and in a car wreck, OK.
98 years old and seized up, nope.
Let people die with dignity, rather than beatin the shat outta em whilst forcin air down their throat.
I saw a man get shocked with a defibrillator 11 times, while being bagged and having that machine doing compressions. If anyone ever gets the chance to watch that, don't.
