Could we really Sleep in Space for years?

In this video, you can find out if we could sleep in space for a long time, to travel for months or years?

Getting around in deep space or even between the planets of the solar system with our current transport technology is a slow business taking months and years. So to save resources, weight and keep the crew from climbing the walls we could put them into a form of suspended animation much like animals that hibernate.

Current medical thinking is that we could do it for maybe months at a time and have this ready in the not too distant future.
