Samuel-Auguste Tissot,
An essay on diseases incidental to literary and sedentary persons
(1768)
“ Take my advice therefore, you men of learning; you will one day repent your austere retirement; but it will be too late to look for a remedy when the danger is at hand; and foresight becomes the wise man: don’t think to excuse your dangerous errors; the experiment is not made upon a vulgar soul, the life of a man of learning is at stake; neither alledge, in excuse for yourselves, the examples of others; nor your own strength, which you break every day; nor vain custom, for we can never use ourselves to a disease ”
