Faria's parents were members of the urban underground Revolutionary Directorate (Directorio Revolucionario Estudiantil; DRE) under Faure Chomón and Rolando Cubela that fought against Fulgencio Batista.

[14] Faria entered and completed his undergraduate studies at the University of South Carolina, receiving a BS degree (Biology and Psychology) and graduating magna cum laude in 1973.

"[9][38] Congress eventually prohibited the CDC from funding gun research and proscribed public health officials from using taxpayer's money in lobbying and participating in politically partisan activities.

[33][39] In March 1990, Faria traveled to El Salvador as part of a mission sponsored by the politically conservative Accuracy in Media (AIM).

After his return to the United States, Faria, who was then serving as chief-of-staff at HCA Coliseum Medical Centers in Macon, Georgia, convinced Dr. Thomas F. Frist, Jr., chief executive officer of Hospital Corporation of America, to send humanitarian assistance to El Salvador.

As a result of Faria's effort, Salvadoran hospitals received a shipment of medications, beds, wheelchairs and physical therapy equipment.

Faria states that longevity is a worthwhile goal and that the compression of morbidity of James Fries should be upgraded from a hypothesis to a theory.

His article hinges on the work of previous investigators but is substantiated by clinical reports and autopsy findings, which were published in Pravda contemporaneously but forgotten in the Soviet archives.

[65] Faria has written or coauthored several chapters in medical textbooks,[66][67][68] and his works are cited and referenced in a number of other books and publications.

[81] His most recent books are Controversies in Medicine and Neuroscience: Through the Prism of History, Neurobiology, and Bioethics published by Cambridge Scholars Publishing on March 23, 2023.,[82] Cuba’s Eternal Revolution through the Prism of Insurgency, Socialism, and Espionage (June, 2023),[83] Stalin, Mao, Communism, and the 21st Century Aftermath in Russia and China (2024) [84] and Contrasting Ideals and Ends in the American and French Revolutions (2024) [85]
