Will that alone save you in a situation like this? Well, no. But buying yourself some time can make all the difference. It can allow you to figure out a way to pull yourself out. Or it may be the time needed for help to arrive. Or at the very least it allows you to enjoy that final sink a little longer than you otherwise could.
I have rendered this animation in a number of resolutions.

Higher resolution means higher quality, but also more data traffic and it is also more demanding on your hardware to decode. Best select the one that matches your device’s resolution most closely. Or a smaller one if it does not play smoothly.
