I feel sorry for the people out there that are spending $30,000 to $50,000 to have their heads or their bodies frozen because they are wasting their money. Some scientist that work for cryonic companies believe that one day we will find a way to revive people by using nano technology to repair the cells that have been damaged by ice crystals. I think we will find a way to revive people, but I believe that if any damage is done to the parts of the brain that store memories there is no point in reviving the person. I think someone will eventually find a way to freeze a body without any ice crystals forming in the cells.
Euthanasia will have to become legal in European and North American countries before cryonic companies that are freezing human bodies can even have a chance at being successful. The fact that a person has to wait until they are legally dead to have their bodies frozen is ridiculous. It increases the chances of cell damage.
