This piece was written by Brother Dr. Alvin Young PM of Acacia Lodge No. 11, Cheyenne. I know of Bro Al’s
experience and asked him to write this. Dr. Young spent more than 40 years in government and universities teaching
environmental toxicology, risk management and public health. While in the Air Force, Colonel Young spent four
years at the School of Aerospace Medicine in San Antonio studying epidemiology and the spreading of diseases.
Brother Kelly Davis PM did some review for this piece.
Thank you, Brothers.
Fraternally,
Tom Hamm, GM
