You are choosing the only possible means which might let you continue to live. And it still remains the only possible mean, even if our suspensions do not improve as we all hope. Even if you believe it is not a very good means, I guarantee that if you are not suspended you will never live again. That is why many of us chose cryonic suspension years ago, despite all its problems. NOW it should be done.
Research is overwhelmingly, very important.
But whatever state cryonic suspension may be in when you yourself find yourself mortally ill, it will remain as before your ONLY choice for further life. You are not risking your life. You are trying to save it. But even if you fail you will have tried.
