Argon (an inert gas that does not react chemically with anything)
makes up approximately 1 per cent of the air we breathe. It is a
very good indicator for a breath of air because it goes into our body
with every inhale, and comes right back out with every exhale.
American astronomer Harlow Shapley calculated the Argon we
exhale spreads across the country within a week, and
completely around the entire earth within one year. With some
of those same Argon atoms returning to be breathed by us again.
Shared by all living things both present, and past, our next breath
will contain more than 400,000 Argon atoms that Ghandi breathed,
come from arguments by diplomats at Yalta, from the recitations
of classic poets like Shakespeare, be in the conversations at the
Last Supper, as well as from the exhalations of the dinosaurs,
whales and sabre-toothed tigers.
"Each breath is a sacrament, an affirmation of our connection
with all other living things, a renewal of our link with our
ancestors and a contribution to generations yet to come."
