I thought Paskey retired from the show because of health problems?
It was during the third year of the series that Eddie decided it was time to retire from Star Trek. He had been having cluster headaches that were further aggravated by the set lighting. In a scene in which he received a "Spock pinch" and was thrown against a railing, he felt his back go out. At this point, Eddie knew he could no longer handle the job's activities.
