looking completely at ease in the water.
Did padi beginners course in taganga north east coast of colombia. pretty much titted up every exercise including the take the mask of under water whilst continuing to breath through your mouth (nb where there IS an air supply) and then replace mask empty it of water using nose and bob´s your uncle. I made the nearly fatal mistake of completely forgetting to not breath through my nose although i had the mantra "dont breath through your nose, dont breath through your nose" continuously running through my head. And coughed like a bastard for ages and hurriedly put back on the mask hoping that I wouldnt do the same thing again. I decided against the advanced course follow up.
