No I don't carry one for now but I know about this and I'm already thinking in that direction since it a Noble thing to do.Maybe I will have to first discuss with my doctor before having one.
I don't think it a bad idea to donate one's organs to those that are till living and needs them either urgently or not when we are dead,after all the person is alresdy dead and the organs therein will become a waste when buried.
It will be a great honor to have the donor organ card it shows one is committed to saving lives not with the huge amount of about 98,000 people only in the US alone looking and waiting to get a kidney,so wanting to donate organs is the best decision one can ever take and the best thing to do to save humanity.
I'm willingly to get one soon .
