The oxygen that we breathe
in
and
out
every minute of every day
is not lost
but shared
re-used
recycled
recirculated.
If we are in the same room –
or sealed hermetically for hours
in the cabin of a plane –
we breathe continuously
the same air,
the oxygen goes from me to you
and back again.
But air currents,
prevailing winds,
the jet stream,
cyclones and anti-cyclones,
all move the atmosphere further
and further still,
so that even if we are
on opposite sides of the globe,
separated by oceans,
it is a statistical certainty
that I still breathe in
atoms of oxygen
that were once
inside
you.
Do they carry your thoughts,
your feelings,
your poetry to me,
or mine to you?
Who can say?
I can but hope it,
as I thank you
for keeping me alive.
