As with any soldier, sailor, or airman who is facing a medical release, the first thing that goes through his mind is financial security. By cutting off these benefits at 65, you're not giving him any hope for financial security and you're increasing Wounded Warriors' base of homeless veterans. You are not staying current with CIMVHR's research, because these veterans will go off the rails at all times if they're not faced with financial security. To cut them off at age 65 is to put an expiration date on your gratitude to the soldier who sacrificed his quality of life, because injuries don't stay the same.
I sustained my injuries at 36 and right now I'm 52 with a skeletal system equivalent to a man who is 65, the eyesight of man approaching 70, and a lung capacity cut in half. I literally would be going crazy if I did not have the financial security to take care of my wife. So, yes, take them past age 65 until the veteran passes, then take care of the wives and the families.
