I mean they, they were huge, but the very early ones and the, the people that were developing them, the companies developing them, all that equipment was based at the London teaching hospitals because we, either we couldn’t afford it or it wasn’t available at that time. And we built a relationship with the Middlesex Hospital, which was our nearest London hospital to use their laparoscopy equipment and experimental laparoscopy equipment to start doing laparoscopic surgery at the zoo. And it was not unusual for us to be using it in the morning. And it then went to be sterilized and used in human surgery in the afternoon, which a lot of people find horrifying, but it actually provide, providing the sterilization process was all right. And then when we had pandas, we had, you know, the last two pandas that were a gift to Edward Heath when he was, when Heath was Prime Minister Heath and the queen, they, the female was very sickly from the moment she arrived. And we used quite frequently used to take her quietly on a stretcher after hours after rush hour to Middlesex hospital x-ray department to see what was going on. And she had a major gut issues to see what was going on Okay. Going on in her digestive system.
