Man, the living sundial, blood changing just
before sunrise and living life within three
rhythmic cycles - earth’s daily turning on
an axis, the moon monthly orbiting earth,
the yearly earth journey around the sun

Pulse, temperature, hormones, blood pressure
and breathing rise and fall in tandem with the
world’s spin – since ability, temper and resis-
tance to infection are controlled by all these
rhythms and sunlight spurs hypothalamus
action which stimulates hormones -

It explains why date of conception has such
a huge influence on temperament
and attitude!
