Within decades, we must close our eyes again. It isn’t a noble, an enlightened way of spending our brief time in the sun, he writes, “to work at understanding the universe and how we wake up to it? This is how I answer when I am asked – as I am surprisingly often- why I bother to get up in the mornings.”
