AIR IS NOT FREE
IT NEEDS TO CIRCULATE(just like us
It varies in quality(just like us
It is easily polluted/diluted
It gets heavy at times
When they say "light as air"
they forget humidity/"heavy"air
And yes-you CAN buy air in a can
as well as in oxygen machines
that dispense pure oxygen
for those of us depleted.
Be Careful!Pure Oxygen may be a brain buzz
but the dilution with nitrogen is essential
We may never get used to pure air
Like "pure"truth-we just make do
with that which we have access to...
