Although Gwyneth did not coin the term "Conscious Uncoupling" - she has certainly popularizing it in the last 72 hours. In the moment of this image however, Ms. Paltrow is exhibiting a very strong SUBconscious uncoupling.
Forty percent of the mass of the human brain is dedicated towards vision. In addition, of the five senses - vision accounts for ninety percent of our sensory input. So the human brain is very visually-biased (even for you "non-visual thinkers" out there) - while the senses of touch, taste, smell and hearing have to share the remaining ten percent. When the eyes are shut - a bit less blood flows to these visual brain and therefor a less nutrients including oxygen gets distributed there. The neuro-chemical activity of the other portions of the brain is thus up-regulated while the visual centers are momentarily down-regulated. Our non-visual senses become sharper - as well as the cognitive and emotional functions. This phenomenon occurs very rapidly - almost instantaneously.
When we kiss with our eyelids shut because we want to heighten the emotional experience of the moment. We want to drink in every ounce - every drop of the kiss. And if we kiss with our eyelids closed - the moment - and therefore the relationship has less emotional impact. Granted we all get distracted from time to time - but kisses should not be one of these times. A highly reliable signal of waning of affection or love in any relationship (spouse, child, parent, platonic friendship, etc.) are eyes remaining open during a kiss.
Although the status Coldplay musician Chris Martin's eyelids at this instant are difficult to discern (they are perhaps slightly opened) in this moderate-resolution image, Gwyneth's are certainly opened. Does your spouse kiss with eyes open? Do you?
