Lester Bush talked to me on the telephone a couple of days ago. He said that he had become acquainted with a psychiatrist, non-Mormon, who had been invited by the Church some twenty years ago to go to SLC to study why so many returned missionaries, or missionaries, had come down with schizophrenia. He had felt it was because the pressure was on them to do a lot of baptisms and they couldn't take it. It was during the baseball baptism period of the 1960s. [[During that period some missionaries attracted teenagers to group sports and told them that baptism was an initiation to join a team.]] He had come to know President Hugh Brown, who he thought had ordered the study. Admired him very much. He was overseeing the study. Why so many had become homosexuals had been lumped with it.
