Grzebski was left in a coma after being hit by a train in 1988. He began to wake from his coma in 1992. Doctors had not expected him to survive, let alone emerge from the coma. He credited his survival to his wife, Gertruda Grzebska, who cared and prayed for him. He was a father of four at the time of the accident. While disabled he gained eleven grandchildren. In an interview on 1 June 2007 with the Polish news channelTVN 24, Grzebski described his recollections of the communist system's economic collapse. "When my familyspoke to me, I could actually hear them but I could not talk back. I could not send them a signal to tell them that I was still alive." He died in 2008.
