Interesting fact for Valentine’s Day: The retina is the only part of the central nervous system that is visible from outside the body.
So when you’re looking deep into the eyes of your true love, you can say…
“Darling, you have the most beautiful central nervous system I have ever seen.”
And if that doesn’t send shivers down their spine, Ode to Psyche by John Keats is possibly one of the most beautiful love poems to feature the mind and brain, as this excerpt shows:
And in the midst of this wide quietness
A rosy sanctuary will I dress
With the wreath’d trellis of a working brain,
With buds, and bells, and stars without a name,
With all the gardener Fancy e’er could feign,
Who breeding flowers, will never breed the same;
And there shall be for thee all soft delight
That shadowy thought can win,
A bright torch, and a casement ope at night,
To let the warm Love in!
