Very nicely done, technically. And the marketing message is both true and useful: Swimming at sea is surprisingly hard, and life jackets make a huge difference.

I was once a very strong swimmer, and back then, I tried swimming 60 feet to shore in water with choppy, 6-inch waves. I wound up repeatedly inhaling water and choking. To combat this, I tried to keep my head high above the water, which was exhausting. After 30 feet, it was clear I was in real trouble, so I called to the rowboat shadowing me 5 feet away and they towed me to shore.

Similarly, cold water will shut me down frighteningly fast—even with a wetsuit and lifejacket, I've been stunned into near immobility after less than a minute of swimming. And I'm somebody who grew up swimming in the Gulf of Maine, which can be frigid (because Cape Cod deflects the warmer Gulf Stream eastward). The actual risk here is cold shock, not hypothermia—rapid vasoconstriction in your limbs will flood your core with blood, causing your heart to work much harder to maintain circulation. It's incredibly draining.

A life-jacket will keep your head above water with minimal exertion. This means that (a) you keep breathing and (b) you remain visible to rescuers. It turns survival from an incredibly strenuous and terrifying athletic event into largely passive floating.

The peripheral vasoconstriction is part of a reflex known as the mammalian dive reflex in which your heart actually slows down, rather than work harder, as soon as your face touches cold water. Muscle cramping is a direct result in the decrease in cardiac output.

This looks very interesting. However for those of us with a slow internet connection, the fact that I can't pause and let it load means my experience is cut every few seconds.

I had the same issue, someone put it up on youtube here https://www.youtube.com/watch?v=wQNNgvvVgi8

Was this a Oculus production?

I got 3mins 28s before drowning and then it said "you tire faster than you think at sea. Always wear a life jacket." I'm gonna go with it being an interesting PSA.

How do you even try to stay afloat? I get 0.

EDIT: Ok, you scroll up. For some reason, it didn't work for me last time I've seen this.

5m02s. But you cannot win in this (not)game. Splendidly done.

If you've got a mouse with a scroll wheel, scroll "down" constantly to stay afloat
