Just for a tease, consider the implications of this excerpt:
Scientists used to think that the dense connections formed among the 100 billion neurons inside our skulls were largely fixed by the time we reached adulthood. Today we know that this is not the case. Nerve cells routinely break old connections and form new ones. The more news we consume, the more we exercise the neural circuits devoted to skimming and multitasking while ignoring those used for reading deeply and thinking with profound focus. Most news consumers – even if they used to be avid book readers – have lost the ability to absorb lengthy articles or books. After four, five pages they get tired, their concentration vanishes, they become restless. It's not because they got older or their schedules became more onerous. It's because the physical structure of their brains has changed.You can read the rest here. But you'll need to excuse me while I begin an effort to fix some old connections and get happy.
I'll be back in a day or two with a post about the Doris Kearns Goodwin debacle at Gettysburg this past Saturday. I think I'll title the post, Academia's Chickens Have Come Home To Roost - At Gettysburg.
