Are yawns passed on from person to person?
Do yawns travel the globe; as people of all nations, all creeds, succumb to the inevitable copying of the yawn they have just observed?
Are yawns like a Mexican wave? A chain reaction? Passing across humanity like an unheard scream?
How many are there? How many are travelling from person to person at any one moment? How many open mouths and deep breaths are currently occurring, right now?
And, what happens if a yawn is unseen? Does the yawn die?
Do yawns only continue to exist in this world because several people seeing a single yawn will replicate it, twin it? Maybe twinned yawns compensate for dying yawns? Maybe this is how the yawn species survives? Clever.
I read recently about an ‘origami robot’ that unfolds itself to perform remote controlled surgery in the stomach. It has just undergone laboratory tests.
The small rectangular robot is ingested in a dissolving capsule and then steered, using magnetic fields, to patch a stomach wall wound or to collect a foreign body, such as a swallowed button battery. Using magnets rather than a tether to direct it, provides greater flexibility and control.
Wow. Science is amazing.
But, how come we can do this, yet…
we can’t cure loneliness?
we can’t stop people worrying?
we can’t stop human beings commiting self abusive behaviour?
we can’t give people their self esteem back?
How many more people worry, or are lonely, or have low self esteem in comparison to those with stomach wall tears or those who swallow batteries?
Come on science, let’s pay attention to the emotional and psychological too. We need you to do great things for us.
