Given the ominous title of this thread, I think we have reason to be worried. Sturgis has been through some very serious, and life-threatening, medical problems, and we don't know what might have recurred or developed to account for his sudden absence almost two months ago.
He knows we are concerned about him, and if he was able to contact us, I think he would have done so.
I think all we can do is hope that he's temporarily without computer access, or currently unable to use a computer, and that he will return here when, and if, he is able.
I continue to send good thoughts and positive vibes his way.
