#1 We Die Every Day
Cells are the basic building blocks of any living species on earth. Together they form tissues, which then form organs. A human body is made of trillions of cells, out of which billions die each day.
An average person loses enough cells each year that could make up for his own weight. This process of self-detonation of cells is essential to make room for newer cells. In other words, each of us is dying every day, every hour, every second of our lives.
