You'll laugh, but the figure of 30 Kg haunted me as I am not exactly Charles Atlas and it is roughly double what I used to carry in rucksacks during my youth. Would I be able to carry such a huge weight?
So I duly weighed out 30 Kg of books and have now returned from a journey to the eight corners of the house carrying them.
Not only was this a success but I don't seem to have popped any hernias ...
... although I may now have to go lie down.
It might all have been a futile exercise with body 1 withdrawn.
Does anyone know if 30 Kg was with or without a head?
