Even experienced keepers make mistakes. I saw a show on TV once years ago. The guy works with cobras for years milking them for venom for research. He was putting one away after milking it. As he was placing the lid on the tub the cobra lived in it struck him in the stomach. He went through the video describing everything he was feeling and went through. He had a friend film the parts when he was passed out from pain. It took over 8 tubes of anti-venom and almost a month in the hospital to keep him from dyeing. After that, he had several surgeries to help with the skin issues and the softball size hole in his stomach. He has a epic scar when all is said and done. That was with someone prepared and anti-venom on hand.
Not for me. Mad respect for anyone who does keep them.
