How real are Blue Spaces in terms of being good for us?
blue space is defined as; ‘health-enabling places and spaces, where water is at the centre of a range of environments with identifiable potential for the promotion of human wellbeing’. (“Blue Space Geographies: Enabling Health in Place” Foley and Kistemann).
Of course it seems obvious that looking at water or blue skies makes us feel better, but why? How much better? 
ON MAGRITTE’S THE VOICE OF BLOOD (Originally published in The Ekphrastic Review)
Art evokes the mystery without which the world would not exist ― René Magritte
I think we should listen more to
old wives and their tales.
Learn how not to get caught in a storm (of fear),
not to enter the (wrong)
doors,
how to avoid the falling stars (or catch a ride).
How to let go (and know)
when trees are silent they are free.
The voice of blood is captured in the geometry of trees and the lie of open windows.
Meandering greys bend in
moonlight’s fortune-telling whispers. Listen.
There is no color without light.
Listen
to the moonlight shape our
monochromatic truth.
Listen, old wives, to our prayers for fairytale endings ever,
ever,
after
grey is washed in morning, graffiti of the light revealed.
