My brother is back in the hospital this morning. There’s something seriously wrong. I’m afraid he’s gone mental. He’s starting to act like Randy Quaid which is completely 180 degrees from his normal. I’m concerned he has a brain tumor, either that or he’s losing his mind. Can people who were previously incredibly mentally tough (he’s been in combat and survived 2 chopper crashes) just lose it that late in life? He just turned 40 which I think is too old for schizophrenia or any of the regular mental diseases.
