Miss Theresa,
I, too, send my sincere condolences on the loss of Glen. I occasionally corresponded with him by email about common interests and he seemed like such a genuine, caring man. He had great hopes for the future - in both his health and the stocks he believed in, I'm sure trusting that the financial future of his family would be rewarded.
As far as this stock, it has been a waiting game. Not knowing what he held exactly, Glen's motto was always "Long and strong" - wait for the technology to materialize. There is a bit of a carrot and stick syndrome with Lifeline, where they continue to promise that the product will be out near-term, but we still are holding our breath around here.
I would say follow your heart. If you decide to sell off the holdings, you might want to do it in metered bits. If you want to take a chance, you'll know by the large account balance that something has finally happened. The name of the product is the iT-bra by Cyrcadia Health, which is for breast cancer detection.
Once again, my heart goes out to you. Glen/Mead had much respect from many here on IHub and, I believe, from all who knew him. Take care!
