If a heartbeat does not denote life, why don't you dispense with yours? After all, you will still be alive. "Life is when you get oxygen to the brain." Oxygen is carried throughout the body by the hemoglobin on red blood cells. (Erythrocytes). They are propelled to the brain via heartbeat, ergo, if the heart is beating, the brain is receiving Oxygen, which, by your own admission is the indicator of life. I am not afraid of science, I appear to be more familiar with it than you.
You can live without a heartbeat. You just need oxygen to the brain. This is how you do heart transplants. You can live without a brain, this is how you become a republican.
