According to relevant media reports, an employee who worked in a freezing institution for 8 months disclosed many details of cryotherapy for "patients" in his book published in 2009, and some practices were accused of being "cruel".

First, the patient draws blood.

The employee disclosed that Alcord's "treatment" of the "patient" was cruel, and even the body of the famous baseball star ted williams was brutally treated. Larry claims that when the body is pushed into the operating room of the foundation, the blood of the "patient" will be drawn and replaced by a chemical mixture, which can minimize the freezing damage. When the head and trunk of the body need to be separated, "I saw it with my own eyes ... they actually used hammers and chisels." Larry said, "I really saw them behead with chisels and hammers."

Second, inject death drugs.

The inside story of the Foundation is that he learned from his colleagues that the Foundation accepted a 39-year-old AIDS patient at 1992. The patient was dying and stopped taking the medicine, but he didn't die. But Larry learned that an experienced employee in the foundation was impatient and simply injected a drug into the patient to stop breathing and accelerate his death.

Third, the inside story is untrue.

When these "inside stories" were exposed, the employee once became a public figure, and Larry was brought to court for this purpose, accusing him of defamation. Finally, the contest between the two sides ended in Larry's bankruptcy and compromise. The employee even admitted that there were some mistakes in the book, including that he initially accused the Foundation of abusing ted williams's body. However, this turmoil has made many people begin to doubt the Alcord Life Extension Foundation.

As of July 3rd/7th, 20th17th, the largest institution has 1 139 members, 370 associate members, and 152 "patients" received cryopreservation technical services.

Some experts said that although the freezing experiment has made some progress in some animals, this method may not be applicable to humans.

In addition, although there are many cryonics institutions in the world, few medical institutions are involved. In the opinion of experts, cryonics is just a new business opportunity, not medicine. Some people also say that cryonics can't be judged as financial fraud or fashion, but more like the gambling of the rich.
