What is the maximum duration of human life? Will we extend it radically? When, as often happens, I am asked this question, I always look at the billions of years that have gone before me and that will follow me.
Those who ask that question are often thinking at a more comfortable time interval, an addition of a few decades maybe. How will it be to live to 120 years? Instead, I think of a different question. What if you lived a billion years?
There were about 13 billion years in which the atoms of the universe did not compose you. There are going to be perhaps hundreds of billions that will not involve you. Between these two time intervals immeasurably larger than the length of your life, living 50 (if tomorrow I go under the bus), 100, 1000 or one million years, in the end, makes no difference.
The stunning wonder of living in a world where, at some point, matter wakes up and opens its eyes to the world, to be its witness and protagonist … This basic human condition already transcends any possible further metaphysical consideration.
That is why the time is now – to think, to do, to be.
