Now, the other crucial point is that in order to complete that process of taking these fuels and converting them into energy, most of the time, you need oxygen. You need air, basically, in your system. Now, it's not actual air. You need oxygen molecules in your system. Comes in through your mouth and your nose, goes to your lungs and distributes via the bloodstream. Oxygen is not a fuel, but like a fire that has no oxygen, you can't actually burn the logs, but when you blow a lot of oxygen onto a fire, basically onto logs with a flame there, then basically it will take fire, it will burn. Oxygen allows you to burn fuel.
