Judging from all that's been said, Alcor patients are not immersed fully in LN2 rather they're inserted head down in the cryostats. The reason being that since the brain is the most important thing to preserve, it will be at LN2 temperature until the cryostat is almost empty of LN2. Back in the 60's Curtis Henderson, who with Saul Kent founded The Cryonics Society of New York, was taking care of 2 capsules (they weren't called cryostats in those days) with 3 or 4 patients in them. One of them contained Ann DeBlasio, I believe the second person suspended by CSNY. She was in the capsule "heads up" as was everyone in those days. Her husband, Nick came out to the cemetary where the capsules were stored, on a regular basis. If he ever found the LN2 level below Ann's head, he raised hell with Curtis. It was such a point of contention that Curtis finally suggested placing Ann "heads down," a very practical solution. Nick's reaction was the same as Ted Williams's buddy at the thought of his friend being upside down. Nick was furious, and it was never done. My question to Charles is at what LN2 level are the cryostats maintained, what is the "normal" level you mention, (half full, quarter full,?) and since heat rises, what is the temperature in the area of the feet? And has there been an assessment of the degree of risk for allowing the feet, and I guess the lower torso also, being at a higher temperature than -196C? Incidentally, in the current issue of The Immortalist, a fine publication, IMHO, there's a photo of the two capsules mentioned, along with a rather leggy Diane Henderson, Curtis's wife at the time. Incidentally #2, I visited the Alcor facility a couple of years ago, it seemed well organized, and have no negative recollections of the place,and the table in the perfusion room sure looked like a stainless steel one.
