Sound to me, it's more like an insurance. I do agree that the cases of usage are rare but no one will know whether we will be the "unlucky" one. At least when things happen, there is a slight hope? Moreover, 20 years from now, no one will know how the technology grows, there might be new discovery of benefits/usage....

haha...i'm still considering actually...but sound to me alot said cyrocord better? is there any statistic? I think it's good to see all the agents first...
