Where the reasons for the difficulties in adaptation encountered by older workers are mainly related to advancement in age, measures in respect of the type of activity in question should to the extent practicable be applied so as to-- ◦(a) remedy those conditions of work and of the working environment that are likely to hasten the ageing process;
◦(b) modify the forms of work organisation and working time which lead to stress or to an excessive pace of work in relation to the possibilities of the workers concerned, in particular by limiting overtime;
◦(c) adapt the job and its content to the worker by recourse to all available technical means and, in particular, to ergonomic principles, so as to preserve health, prevent accidents and maintain working capacity;
◦(d) provide for a more systematic supervision of the workers' state of health;
◦(e) provide for such supervision on the job as is appropriate for preserving the workers' safety and health.
