Hi,
Just a curious question. We all know that one of the tricks to conserving gas/air is to inhale and exhale slowly and deeply. I was curious - how long do you take (in secs) to fully inhale and exhale?
(On the odd occasion I've got a headache immediately after surfacing, and have wondered if I've breathed too slowly)
