Armstrong's family described him as a "reluctant American hero". He kept a low profile later in his life, leading to the belief that he was a recluse. Recalling Armstrong's humility, John Glenn, the first American to orbit Earth, told CNN: " didn't feel that he should be out huckstering himself. He was a humble person, and that's the way he remained after his lunar flight, as well as before." Armstrong turned down most requests for interviews and public appearances. Michael Collins said in his book "Carrying the Fire" that when Armstrong moved to a dairy farm to become a college professor, it was like he "retreated to his castle and pulled up the drawbridge". Armstrong found this amusing, and said, "...those of us that live out in the hinterlands think that people that live inside the Beltway are the ones that have the problems."
