When you have a relative who is seriously ill, the majority of individuals would never consider "pulling the plug" or taking them off of life support unless they had flatlined, meaning that they have no heart function, and their heart cannot be restarted. The truth is that the vast majority of people who have flatlined can remain alive for at least another week without a fully functioning heart.
The most critical part of the body is not the heart, but the brain. The brain does not need blood, and therefore, it can continue to function while the heart is healing. In fact, one can ask a section of the heart to take over the function of another section, so that the affected section can heal.
In Jewish culture, a person is not considered dead unless they are brain dead, have flatlined, have no reflexes, are unable to breathe independently or with a respirator, have no bowel movement, have no dilation in the pupils in response to light, and are incapable of perspiring in response to heat. Only when all these factors are present are they then taken off of life support. The same should be true for every other individual, regardless of race, sex, class, culture, or place of origin.
