@McTag,
Have you never experienced the astonishment of how often you are astonished. Each astonishing happening seems to me to distract people's attention from how often astonishing events occur.
It's deceptive of course. Astonishing events are probably lower in frequency than they have ever been in history but television, and media generally, by bringing the remote and unusual into the individual living space, has distorted perceptions to such an extent that millions of people whose daily lives are totally devoid of anything astonishing are astonished at an alarmingly increasing rate.
I was astonished myself just now, not enough to go to the bottom of the stairs mind you, that Kirsty Walk was so expert on the housing of families who had failed to pay their rent, events on the borders of Turkey and Syria and the wider implications thereof, the Spanish bailout and Catalan independence, the tax fiddling of BBC employees and the west coast high speed rail link. In 50 minutes.
Tomorrow night it will be something/s completely different. All astonishing.
