<font color='#F52887'>OK, you pedant. what I am saying is that you put He into your cylinder then top up with Air. In trimix you use He, O2 (or EANx) and air.
If you want to be really anal you could say that we are breathing Trimix effectively because those gasses exist in (differing quantities) in the air that we breathe.
