Do you want to live forever? i guess almost everyone would say "No way!".. mostly we have no desire to outlive our loved ones and to endure the aches and pains of old age on our own.

But what if you could die, then come back hundreds of years later with a new body? What if you weren't alone? What if your children, your spouse, even the family pet could come back with you?

Maybe then u ll consider.

This scenario one day can become a reality. It's called cryonics. In short, it's the deep-freezing of human bodies immediately after death for preservation and possible revival in the future. Believers call themselves cryonicists and they pay big money. It costs $150,000 for the whole body and about half that for just the brain and head. There are discounts for entire families and pets.Sure you've heard of cryonics. Listening to some of the cryonicists' arguments make it sound less skeptical. They point to the exponential rate of technological advances. Dialysis allows people with kidney disease to live longer, healthier lives. Operating on fetuses still in the womb is commonplace. Brain surgery can be done without incision.Cryonicists see the transport of chilled organs and tissue for transplants as a step in the right direction. Doctors at Harvard Medical School are working on a process similar to suspended animation. They can take severely injured pigs, the size of humans, and slow down their body's functions, just long enough to mend their traumatic injuries. When the pigs are revived they show no sign of cognitive loss.To be clear, most doctors say it's unthinkable that cryonics will ever become a reality. After all, we're still talking about bringing someone back from death. How much would you pay to buy immortality?
