Those considered as doing light work are persons who sit or stand at
their employment without any great degree of activity. They include
stenographers, dressmakers, milliners, teachers, clerks, shoemakers,
tailors, machine operators, elevator operators, and conductors.
Moderate work involves a little more activity than light work, but not
so much as heavy work. Professional cooks, professional housekeepers,
housekeepers in their own homes, professional chambermaids, waitresses,
masons, drivers, chauffeurs, plumbers, electricians, and machinists come
under this class.
Persons doing heavy work are the most active of all. They include
farmers, laundresses, excavators, lumbermen, miners, metal workers, and
soldiers on forced march.
39. To show the variation in the amount of food required according to
body weight, Table IV is given. The scale here presented has been worked
out for two persons who are normal and whose weight is correct, but
different, one weighing 130 pounds and the other 180 pounds. It is
assumed, however, that they are occupied in 24 hours with activities
that are identical, each one sleeping 8 hours, working at moderate labor
for 8 hours, walking 2 hours, standing 2 hours, and sitting 4 hours.
