What is killing young healthy Americans? Edward Dowd, a former Wall Street analyst and BlackRock portfolio manager, examines the epidemic of sudden deaths in America. Throughout his stock picking career, he utilized pattern recognition to get ahead of his peers and the street before his bullish or bearish thesis became consensus. Early in 2021, he noticed a rise of news anecdotes about sudden deaths among very fit athletes and other seemingly healthy young people across the country. His thesis was simple: What changed in 2021? . . . A mass vaccination campaign for Covid-19 was his conclusion. Over the course of 2021 and 2022, Edward amassed evidence from the insurance industry, funeral home industry, and government databases that excessive deaths among working-age Americans have increased in 2021 versus 2020 when vaccines were not available. This book will introduce you to some of the tragic stories that have occurred the last eighteen months and lay out the metadata to show readers that something profound changed in 2021 to cause the sudden rash of young deaths with Cause Unknown!.
