Cryonics is a method of bodily preservation in which human remains are frozen (typically at temperatures hundreds of degrees below 0 Celsius) with the hope that improved technology will allow for that individual to be resuscitated in the future. Debate exists over the practicality of such resuscitation, and many scientific experts believe it to be impossible. Nonetheless, around 250 bodies are cryopreserved in the US as of 2014, and about 1500 people have arranged to have their bodies cryonically frozen after their death.
