Understand! If I had had the money I would have jumped on the Marodyne bandwagon too. Fear is a huge motivator! But now I am glad I waited and I think the choices I have made have been good ones. But again waiting for the Vibmor clinical trial results. I am working towards implementing the full LIftmor exercises which have proved that HIIT does build bone. For those who can't exercise (strength training) perhaps the Marodyne would help. Just know that NASA does not and never has used the Marodyne for their astronauts. Instead they use strength training machines to build bone.
