@drbahaadmourInside the Heart | Blood Leaves and Remains 🔄🫀 ────────── Your heart does not empty completely with every beat. 🔬 The left ventricular ejection fraction, or LVEF, measures how much blood the left ventricle pumps out during contraction.

The Voluntary Human Extinction Movement argues that the most compassionate and moral thing that humanity can do is to stop having children and let ourselves go extinct. They even have a motto, 'May we live long and die out.' The movement was started in 1991 by Les Knight, and it says that if you look at what humanity has done to the planet - the mass deforestation, the extinctions, and all of the plastic in the oceans - then you have to reach the uncomfortable but logical conclusion that the Ear
