This personal anecdote doesn't really add to this conversation in a constructive way.
But, for sake of argument, it assumes a few things:
1) That your lungs are healthy enough to hold your breath for >= 1 minute (not all are)
2) You actually have the opportunity to breath in a lungful of oxygen-rich air (depending on the situation/timing, this might not be the case)
3) You have your wits about you while a very stressful situation unfolds around you (let's argue that you, personally, are cool and collected under pressure - this; however, is not universally true for all other passengers)
