[We] ought to show peculiar zeal…in taking precautions for their safety. I for one have done all that lay in my power, and have not thought it beneath me to step into workshops of the meaner sort now and again and study the obscure operations of mechanical arts.
I have noticed bakers with swelled hands, and painful, too; in fact the hands of all such workers become much thickened by the constant pressure of kneading the dough.
Not only in antiquity but in our own times also laws have been passed…to secure good conditions for workers; so it is right that the art of medicine should contribute its portion for the benefit and relief of those for whom the law has shown such foresight…
Those who work standing … carpenters, sawyers, carvers, blacksmiths, masons … are liable to varicose veins … [because] the strain on the muscles is such that the circulation of the blood is retarded.
All sedentary workers … suffer from the itch, are a bad colour, and in poor condition … for when the body is not kept moving the blood becomes tainted, its waste matter lodges in the skin, and the condition of the whole body deteriorates.
Standing even for a short time proves exhausting compared with walking and running though it be for a long time … Nature delights and is restored by alternating and varied actions.
