Oh, I am so sorry to hear this news. During one of the worst times of my life, I was at home recovering from neck surgery in 2006 and remember reading over and over many of the posts by so many of the true educators on this site. Felix was one that I knew I didn't have to worry about his advice. There were some long, slow, days that passed so much easier during that time because of the fine folks here & Felix was at the top.
He will not be forgotten.
