Just this month I threw mine out. And it wasn't the newest one. I refused to sign the one from last year because it didn't even show that it was a scriptural stand that we were taking. After the watchtower study about a year ago, everyone walked away confused and didn't know where they stood anymore, either. The society has gone back and forth to much and frankly, they don't even know where they stand.
Being a trained witness I have an aversion to receiving someone else's blood. The idea is rather disgusting but I am do not think that it is something that the bible condemns. There have been quite a few discussions on this board that have shed quite a bit of light on it for me. My family and I have discussed it length and all of us think that it is a rather questionable issue. I am definately not averse to storing my own blood for later use but the blood will only last for a few months. If my son were in need of medical attention, I would ask the doctors to try everything possible before a blood transfusion, but would give him one if necessary. It is hard to get over being brain washed for so many years but I am trying to break the bindings.
Jesus gave blood to save humanity, obviously he and Jehovah valued life enough to do so.
