Back (pun) to the question, sorry your thread got hijacked Al & no one is giving you any sympathy, I know what it's like, crook back that is, not lack of sympathy. :D
I actually put my back out throwing paper when I was 18. :eek:
I was unloading a pallet of paper for the RAAF school of Radio Library.
They had parked a pallet load of paper as close as they could get it to the door & a handful or troops had formed a bucket brigade to unload the paper into the library & onto the shelf. I was the first in the chain so I was picking up the catons & throwing them to the next bloke. As the pile worked down, I had to bend down further each time to get the next box. I was grabbing boxes & tossing them up & sideways to the next bloke without standing up first.... F'n snap. wam bam thank you mam, down I went in a pile of.... paper. Hospital for a week, haven't been the same since. :(
