Sweet, Refreshing Oxygen
It’s nuts that the human mind can come up with incredible things. We’ve learned to fly, photograph distant galaxies, and create world-ending bombs. However, without the simplest things like water, food, and oxygen, we wouldn’t have made it past infancy. This just shows how powerful yet fragile the human mind and body can be.
Something everyone should memorize is the Rule of Threes. Although it varies from person to person, the rule is three minutes without oxygen, three days without water, and three weeks without food. Unless you’re an action movie star, holding your breath for longer than three minutes can lead to the beginnings of brain damage.
