this is one of my personal favorites fron the new inventors

I had to have my back fused early 2005 at the royal adelaide hospital and they were testing these

, whats ironic is if we'd had one of these when I was working, (Army Medic working in a military hospital), I would never have injured my back and wouldnt have had to have my back done
Talking to one of the hospital porters earlier this year about the bed lifter and he was telling me when they first tested it , the Management of the hospital said No to buying a bunch of units - Then they saw the new inventors show with it and said "What a great Idea , should we get some" the answer to which was 'What do you think we've been useing and asked for way back" , the hospital's got something like 50 units now
