I prefer a mix of gases.

Don't like the oxygen poisoning and burning feling in my lungs when breathing pure oxygen.

You know how it is... everyone needs their dose of fresh Perri-air.

Oxygen is a big bunch of hot air if you ask me...

I don't give it much thought. It just happens.

Also, we breathe in everything in the air. It's just that the oxygen is the only one we use. 

Only if it's the chemical-free, organic stuff.

I like oxygen I think it's really great
If I didn't have O2 I would be a boring date
Cause I'd be dead.

Astronauts on space suits often breath pure oxygen. The thing here is the absolute pressure of oxygen, not partial pressure, if every other gas on the atmosphere besides oxygen disappeared you would breathe just fine before dying as the weather goes haywire.

Taking something that's rhetorical in a literal way. Classic.

I´m not sure..... I´d rather drink it, but it may be a little dangerous...
