mind are contained in its anatomical structure, few neuroscientists will comment directly upon the topic of cryonics due to its speculative nature. individuals who intend to be frozen are often "looked at as a bunch of kooks". cryobiologist kenneth b. storey said in 2004 that cryonics is impossible and will never be possible, as cryonics proponents are proposing to "over-turn the laws of physics, chemistry, and molecular science". neurobiologist michael hendricks has said that "reanimation or simulation is an abjectly false hope that is beyond the promise of technology and is certainly impossible with the frozen, dead tissue offered by the 'cryonics' industry". anthropologist simon dein write that cryonics is a typical pseudoscience because of its lack of falsifiability and testability. in dein's view cryonics is not science, but religion: it places faith in non-existent technology and promises to overcome death itself. william t. jarvis has written that "cryonics might be a suitable subject for scientific research, but marketing an unproven method to the public is quackery". according to cryonicist aschwin de wolf and others, cryonics can often produce intense hostility from spouses who are not cryonicists. james hughes, the executive director of the pro-life-extension institute for ethics and emerging technologies, chooses not to personally sign up for cryonics, calling it a worthy experiment but stating laconically that "i value my relationship with my wife." cryobiologist dayong gao states that "people can always have hope that things will change in the future, but there is no scientific foundation supporting cryonics at this time." while it is universally agreed that "personal identity" is uninterrupted when brain activity temporarily ceases during incidents of accidental drowning (where people have been restored to normal functioning after being completely submerged in cold water for up to 66 minutes), one argument against cryonics is that a centuries-long absence from life might interrupt the conception of personal identity, such that the revived person would "not be themself". maastricht university bioethicist david shaw raises the argument that there would be no point in being revived in the far future if one's friends and families are dead, leaving them all alone; he notes, however, that family and friends can also be frozen, that there is "nothing to prevent the thawed-out freezee from making new friends", and that a lonely existence may be preferable to no existence at all for the revived. in fiction suspended animation is a popular subject in science fiction and fantasy settings. it is often the means by which a character is transported into the future. a survey in germany found that about half of the respondents were familiar with cryonics, and about half of those familiar with cryonics had learned of the subject from films or television. in popular culture the town of nederland, colorado, hosts an annual frozen dead guy days festival to commemorate a substandard attempt at cryopreservation. notable people corpses subjected to the cryonics process include those of baseball players ted williams and son john henry williams (in 2002 and 2004, respectively), engineer and doctor l. stephen coles (in 2014), economist and entrepreneur phil salin, and software engineer hal finney (in 2014). people known to have arranged for cryonics upon death include paypal founders luke nosek and peter thiel, oxford transhumanists nick bostrom and anders sandberg, and transhumanist philosopher david pearce. larry king previously arranged for cryonics, but according to inside edition, later changed his mind. disgraced financier jeffrey epstein wanted to have his head and penis frozen after death so that he could "seed the human race with his dna." the corpses of some are mistakenly believed to have undergone cryonics – for instance, the urban legend suggesting walt disney's corpse was cryopreserved is false; it was cremated and interred at forest lawn memorial park cemetery. robert a. heinlein, who wrote enthusiastically of the concept in the door into summer (serialized in 1956), was cremated and had his ashes distributed over the pacific ocean. timothy leary was a long-time cryonics advocate and signed up with a major cryonics provider, but he changed his mind shortly before his death and was not cryopreserved.
