Matthew McConaughey to bear more fruit

Matthew McConaughey says the birth of his son will help bring a little joy to others in the world someday. The actor kept the placenta from the July birth of his son and plans to plant it in an orchard, he tells CNN's House Call with Dr. Sanjay Gupta in an interview scheduled to air in two parts on August 9 and August 16. McConaughey says he hopes it will fertilize the land, a ritual long followed in several cultures. "It's going to be in the orchards and it's going to bear some wonderful fruit," he says, according to an interview transcript. "When I was in Australia, they had a placenta tree that was on the river ... and all the placentas of all that tribe, all that clan, whatever aboriginal tribe that was, all the placentas went under that one tree and it was this huge behemoth of just health and strength. "This tree was just growing taller and stronger above the rest of Mother Nature around it. It was gorgeous." McConaughey also says he and his girlfriend Camila Alves have enjoyed integrating their new baby, Levi Alves McConaughey, into their lives. Already they've started introducing him to the "sights and the sounds" of the world including a John Mellencamp concert. "You're never told in our house, 'Shh, Levi is sleeping.' No. Get used to the ambiance. Come with us. That's how I was raised," he says.
