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. Pressing the eyes of fish will paralyse them
5. The body can be heroic in battle; 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
