When you exhale, you mostly breathe out carbon dioxide, which is deadly over time. CPR isn't long term, it's literally used to kick-start your hearth.

Try breathing in and out of a balloon several times and tell me you won't get dizzy if you don't believe me.

I sure am considering i have this damn SARS mask on

Your body isn't that efficient, this is why we can breathe into another person to save them during CPR. Things everyone can know, since it's the age of the internet.

Unless your walking.
