Hi folks. My first time posting on this forum. I've been impressed with what I've read thus far. Here is a link, that in my opinion, is very good regarding practical matters related to blood: http://www.bloodbook.com/world-abo.html There is a plethora of information there that may intrigue those of you who have limited information about Blood, its components, autologous blood transfusions, and many other questions. I have found it so useful, that it actually inspired me to go to my family physician and get my blood, typed. Good thing too. My blood type, being rh-negative, was an important finding. There was a posting regarding the Hepatitis concerns. Given all of the recent on-going research into blood based contaminates, hematogology is improving on a daily basis. Everything is being done to decrease the possible risks involved in receiving blood based products. If we didn't have hematology, I dear say, mankind at large, would be at a horrible loss. Find out your blood type. Mark it down. Keep it with you. Check the link I posted above: it's wonderful, informative, and has many answers to the questions most of us ex-JWs could ever want.
