				Has every breathing innovation already been made?
			 
 
			You got your scuba, your CPAP, the iron lung, your replaceable cartridge respirators, your fancy deep-sea diving helmet, space suit helmets, paint booth masks with air.  Is there any occupation or hobby that needs a breathing innovation that hasn't been invented, or that needs improvement?
