Summarize the following:
Water flows downhill, so you should look for bodies of water in depressions in the earth and valleys. If you’re in a mountainous region, there’s a reasonable chance that if you walk parallel to a mountain you’ll find a stream or river eventually. If you do find a body of water, you should build your shelter near it. Don’t build the shelter on the water’s edge, though, because chances are that (possibly dangerous) animals will frequent the area to quench their thirst. You should always boil any water that you collect from a body of water in nature. If you have a metal container, you can put it on your fire to boil for at least 20 minutes to sterilize it. If you don’t have a container you can put onto a fire, you can still boil the water with a boiling pit.   To boil water with a boiling pit, dig a hole approximately 2 feet (0.61 m) long by 2 feet (0.61 m) wide by 2 feet (0.61 m) deep next to your campfire. Then, separate out the clay from the soil (it will be sticky and reddish), and line the hole with the clay, making sure there are no cracks or openings in the layer of clay. Then, use a container like a hat or a shoe to transport water from your water source to the boiling pit until it’s full Once your pit is full, heat rocks on your campfire. Heat them for approximately 10 minutes, then start dropping them in the pit. Rotate freshly hot rocks with ones in the pit that have cooled down until you have a steady boil for 20 minutes. Before you go to sleep, dig a hole that is approximately 1 foot (0.30 m) long by 1 foot (0.30 m) wide by 1 foot (0.30 m) deep. The hole should fill with water overnight. The water will be muddy, so you should strain it with a piece of cloth like your shirt.  If you don’t have a container to strain your water into, you can use your shirt to soak up water and then wring it into your mouth. The shirt should hold on to most of the mud. In the mornings, you can use your shirt to collect dew. Just press it into the ground and it should soak up some water that you can wring into your mouth. During the day, trail your shirt behind you through the underbrush. It should pick up some moisture from the leaves that you can also wring into your mouth. If you see ants climbing trees, there’s a good chance they’re traveling toward a deposit of moisture that is collecting in one of the tree’s grooves. Follow the line of ants to their destination on the tree and, if it’s within reach, press your shirt against the water deposit to soak up the moisture. Then you can wring the water into your mouth. Be careful not to swallow any ants using this method; they could have pincers.

summary: Locate a body of water like a river, stream, lake, or pond. Sterilize water from lakes, ponds, streams, and rivers. Dig for water if you can’t find a lake, pond, stream, or river. Use your shirt to collect moisture from the ground and plants if you can’t find other water. Follow ants climbing trees to find pockets of moisture in the bark.


Summarize the following:
Thinking of skipping breakfast? Don’t do it. Your body needs the salt and sugar to keep you standing up. In fact, if you keep your blood pressure and glucose levels stable, barring any other outlying physical condition, syncope (fainting) is hopefully completely avoidable. To keep your body working normally, all you may have to do is eat (and drink) regularly. That said, some people do suffer from postprandial hypotension, which can lead to fainting. That’s a fancy word for your blood pressure dropping after you eat too much. Your blood starts congregating in and around your stomach, leaving none for your heart and brain – the perfect recipe for a fainting spell. If this sounds familiar, it might help to eat frequent, low-carbohydrate meals. Eat regularly, but don’t eat too much at one time. Another reason some people experience fainting spells is because they’re overly fatigued. It could be because you’re not sleeping enough or you exercise too much – both states can affect your blood pressure and get your body off-kilter. If you’re exercising too much, you may not be getting enough liquids either (you’re sweating them all out). Make doubly sure you drink plenty if this describes you. Between dehydration and overexertion, you could be asking for trouble. Some people have triggers when it comes to fainting, and it doesn’t take fainting too many times to figure out what that trigger is. If you know what causes you stress and makes you anxious, avoiding it may be all you have to do. Needles, blood, and even more personal topics can bring about the urge to faint. The heart starts pumping profusely, you start sweating, your breathing changes, and all of a sudden you’re down for the count. Can you think of any possible triggers for the way you’re feeling? Heat is another culprit when it comes to fainting. It can dehydrate your body, shut down your systems, and spell disaster for vertical consciousness. If you’re in a stuffy, overheated, or crowded room, you may just have to leave. The fresh air will awaken your senses, your blood pressure will rise, and you’ll be back to normal before you know it. Crowds don't generally help. If you know you're going to be in a crowded, stuffy area, prepare by eating a good breakfast, wearing light clothing, bringing a snack, and always knowing where the nearest exit is should you need it. In addition to caffeinated beverages, alcohol should also make the “avoid” list if you’re worried about fainting. It, too, is dehydrating, can lower your blood pressure, and send you to the ground. If you do drink alcohol, stick to one drink a day. And if you haven’t eaten or drunk much that day, be sure to combine that drink with some food and other non-alcoholic beverage. If you have ever watched a military event where soldiers stand for long periods, usually one or two end up fainting. It’s not locking the knees as such that causes faintness, but the immobilization of the leg muscles.  You might try a technique called “tilt training,” which involves training your muscles over the course of weeks to combat the urge. You simply stand with your back and head against a wall with your heels about 6 inches (15 cm) out from it. Do this for about 5 minutes every other day. Slowly increase the time up to 20-minute sessions. It sounds simple, but this stance can help uncross the wires in your brain (the vagus nerve) that lead to fainting.
summary: Eat regularly. Avoid excess fatigue. Keep your stress and anxiety to a minimum. Stay in comfortable, cool environments. Avoid alcohol. Don’t lock your knees.
