Nature no longer can regulate the mortality rate. Diseases that formerly sounded weird and foreign to the ears are now killing people today. According to a WHO report released in 2016, about 40.5 million people died due to diseases caused by unhealthy lifestyles. Since then, the numbers have risen dramatically, and the pandemic will demonstrate this in 2020. Ultimately, a virus can only kill someone if the body's immune system cannot fight off the antigen. Unfortunately, not everyone is aware of lifestyle diseases, as most people believe they are caused by heredity or appear out of nowhere.
