Eh sir...pano kung scuba diving? e di hahabulin mo pa sa ibabaw yung phone. joke :D
hahahah
well, it's hard to scuba dive more than 100 meters. you need to decompress along the way. scuba diving 300 meters with an open circuit takes 12 hours. rowing a boat for 300 meters takes minutes, or a couple of hours if you're extremely out of shape heheh.
