I believe that the brain has evolved over millions of years to be responsive to different kinds of content in the world. Language content, musical content, spatial content, numerical content, etc.
– Howard Gardner
The forties are the time when you begin to take notice of certain aches and pains. Your body and brain behave in inexplicable ways: Less hair on your head, more in your ears and nostrils. More memories in the bank, less synaptic firepower with which to access them. Gravity has started to show its inexorable pull.
– Hampton Sides
