Reducing the cost of a cryonics service below the amount of this insurance effectively reduces the upfront cost of cryonics to zero. The question then becomes not one of money, but of preference. Do you wish to be buried in the local cemetary or have your brain/head frozen for what is effectively the same out-of-pocket expense? Advantages of storing only the brain, as opposed to the entire head include, no negative PR, potentially greater cryoprotectant infusion/protection, and lower storage costs. The main negatives would be possible increased physical damage during handling. A further side note on storage costs: Dehydrating a brain during shipment in an concentrated cryoprotectant bath would effectively reduce storage costs by shrinking the brain volume. A further benefit here could be cheap vitrification, with potentially far superior preservation of cellular structure during freezing. Note: Although it is commonly beleived whole brain cryopreservation is the "lowest" you can go. This is not in fact the case. Surprisingly good functional capacity is retained in right handed people, who have had their right hemispheres destroyed. With a little dehydration, one could hold what is effectively one's soul in the palm of the hand! Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=12174
