Trivial knowledge might save your life one day

While the term "trivial" often implies something of little importance, there are certain seemingly small or common-sense pieces of knowledge that can be quite valuable in emergency situations. Here are a few examples:

Stop, Drop, and Roll: In case your clothes catch fire, the basic technique of stopping, dropping to the ground, and rolling to smother the flames can be crucial.

The Rule of Threes: In survival situations, remember the "Rule of Threes": you can survive approximately three minutes without air, three hours without shelter in extreme conditions, three days without water, and three weeks without food.

Emergency Signals: Learn and remember basic emergency signals, such as the international distress signal SOS (...---...), or signaling for help using three of anything (three loud shouts, three whistle blasts, etc.).

Navigating by the Stars: Knowing how to identify basic constellations or using the North Star for navigation can be useful if you're lost and without a compass.

Finding North with a Watch: In the northern hemisphere, point the hour hand of your watch at the sun. South is then halfway between the hour hand and the 12 on your watch. This can help you determine north.

Basic First Aid: Knowledge of simple first aid techniques, such as how to stop bleeding, perform CPR, or treat shock, can be life-saving.

Water Purification: Knowing how to purify water using basic methods like boiling, using purification tablets, or creating a makeshift filter can prevent waterborne illnesses.

Basic Knots: Learn a few essential knots. Knots can be useful in a variety of situations, from setting up a shelter to securing gear.

Identifying Edible Plants: A basic knowledge of local flora can help you identify edible plants in case you find yourself without a food source.

Swimming Techniques: Basic swimming skills and water safety knowledge can be critical in situations involving water, such as crossing a river or escaping a sinking vehicle.

While these may seem trivial in everyday life, they can be invaluable in unexpected situations. It's always good to be prepared and have a basic understanding of survival skills.
