1. Shelter yourself. Exposure can kill faster than thirst or hunger.
2. Do not drink urine. Or sea water. Or bird blood
3. Do not eat jellyfish. Or fish that have spikes. Or fish that have parrot like beaks. OR that puff up like balloons.
4. Turtles are an easy catch and make for excellent meals. Their blood is a good, nutritious, salt-free drink; their flesh is tasty and filling; their fat has many uses; and the castaway will find turtle eggs a real treat. Mind the beak and the claws.
5. If a castaway is injured, beware of well-meaning but ill-founded medical treatment. Ignorance is the worst doctor, while rest and sleep are the best nurses.
6. Put your feet up at least 5 minutes every hour
7. Do not go swimming. It wastes energy. Besides, a survival craft may drift faster than you can swim. Not to mention the danger of sea life. If you are hot, wet your clothes instead.
8. As long as no excessive water is lost through perspiration, the body can survive up to 14 days without water. If you are thirsty, suck a button.
9. Beware of far-off clouds that look like mountains. Look for green. Ultimately, a foot is the only good judge of land.
10. Don’t let your morale flag. Be daunted but not defeated. Remember: the spirit, above all else, counts. If you have the will to live, you will. Good luck!
