On the BBC news at present is a story about a 14 year old girl from the UK who has sadly died of cancer, but has chosen to be cryogenically preserved in the US in the hope that in the distant future, science will find a way to cure the cancer and resuscitate her frozen body.
The chances of this technique ever becoming a practical reality are very remote at present and it would take major breakthroughs in technology. However, the professor in charge of tissue banking at the University of Bristol, says that although there is little chance of it happening based on current knowledge, he believes "you can never say never in science".
Hypothetically, if in the future, science does manage to 'resurrect' bodies from a frozen state, without brain damage or other physical problems, so the person could live again with the same personality and memories as before, how would religious believers deal with the issue?
Christians who believe the soul goes to Heaven (or hell?) after death would presumably have some complex theological questions to tackle, but I'm not sure how JWs would react?
