Your existence matters

In a universe where the passage of time
Can be measured by the disappearance of a mountain
One touch of a birds feather once in a thousand years
Where the galaxies are numbered in trillions of trillions
And in each are countless stars and planets like our own
You think your existence matters one jot?

The answer? Of course it does, why else would you
Be gifted a brain capable of understanding the Universe,
A brain which itself contains eighty-six billion neutrons
And it is estimated a whopping great 500 trillion synapses
You are as marvellous and as complex as all the galaxies
And all the stars and planets and every atom put together.
The human brain has some 8.6 x 1010 (eighty-six billion) neurons. Each neuron has on average 7,000 synaptic connections to other neurons. It has been estimated that the brain of a three-year-old child has about 1015 synapses (1 quadrillion). Estimates vary for an adult, ranging from 1014 to 5 x 1014 synapses (100 to 500 trillion).
