Welcome to this website.
I am David F Marks PhD, psychologist, author and editor; 
my hobbies are nature, photography, film and books.
This site is for people who are curious about behaviour.
The focus is the homeostatic regulation of behaviour,
body and mind.

Homeostatic regulation is a singular unifying principle in all health protection and illness prevention. Health is regulated by homeostasis, one of the distinguishing features of all living things; it preserves life when in balance; it removes life when imbalanced; when not present at all, a system cannot be living… Homeostasis operates at all levels of living systems: in cells, tissues, organs, organisms, societies and, some have argued, in biodiversity and the planet as a whole.
