The Hunter-Killers Inside Us

T cells are a form of white blood cells that track down and destroy foreign parasites inside our body. Turns out they are very efficient predators, using stalking techniques similar to those used by sharks, both those that swim in the sea and those that inhabit Wall Street. It seems to me we are just beginning to understand the depth to which the natural world is vertically and horizontally integrated. William Blake said it eloquently in his poem, Auguries of  Innocence:
To see a World in a Grain of Sand
And a Heaven in a Wild Flower,
Hold Infinity in the palm of your hand
And Eternity in an hour.
