All biological factors produced by each
organism ensure its normal working and life
maintenance.
The production
of biological factors
is
indispensable
for
the maintenance of normal physiology.
They
decrease with age.
Diseases
of
aging
represent consequences of life maintenance
system failures.
The organism's glandular system is an
essential part of the maintenance system for
both men and women.
Glands
progressively stop functioning.
The
ovaries, testicles, thyroid,
pancreas, pituitary, and epiphysis
secrete the main hormones.
In man,
male hormone
secretions diminish year to year after forty
(and sometimes even before).
Cells produce other hormones.
The liver secretes a specific growth factor
(IGF).
Kidneys secrete a hormone, erythropoietin,
that causes red blood cells' production by
the bone marrow.
Today genetic engineering
produces
red corpuscles, white cells, and platelets. These products will be given
intravenously in vain to people who have not
looked after their life maintenance system,
especially from forty.
