Q: When you sit, keep your spine straight under your neck with your feet flat on the floor. Avoid slouching and keep your eyes facing forward. When standing up, keep your spine straight with your back directly under your legs. Avoid slumping forward or leaning against the wall to keep your spine in a neutral position. Counterintuitively, hard-backed chairs are actually better for back pain than soft sofas or cushioned chairs. It's easier for your spine to become misaligned if the back of the chair isn't holding it in place. When you go to bed, you can lie on your side or back, but avoid sitting up in bed or lying face-down. For your side, slide a pillow between your knees and bend then at 35- to 45-degree angle. If you're lying on your back, slide a pillow directly under knees to alleviate the pressure on your back. When it comes to your mattress, a firm mattress with a soft top is ideal. If it weighs more than 25 pounds (11kg) and you have back pain, just skip it or enlist someone else to help you carry it. Otherwise, bend with your knees to lower yourself down and avoid bending your back forward to lift something up. Use your knees to bring yourself back up and keep your spine as straight as possible. Lifting belts are not really proven to prevent back injuries, so don't rely on a one to protect yourself. They may be able to alleviate some lifting pain, though. Keep the object that you're lifting centered in your chest. If you hold it at your side, you may increase the risk of a back injury. When you lift with your knees, you are not using your back as a lever. Instead, you're using it as a crane and your legs doing most of the work.
A: Maintain a proper posture to avoid straining muscles in your back. Lie on your side or back when you sleep and prop your feet up. Lift with your knees and avoid carry really heavy stuff.

Article: In order to measure out your 4 gallons, you need to put it somewhere. As John McClane rightly deduces, you couldn't possibly fit it in the 3-gallon jug, which means the right answer must involve getting the right amount of water in the 5-gallon jug. The solution does not involve bringing in another jug, or eyeballing the water levels perfectly, or finding fractions of jugs. You have two jugs and an unlimited supply of water. How can you use just those things to get to 4 gallons? More specifically, how can you use 3 and 5 to get to 4? Unlimited water means you can use or pour out as much as you want. You are not able to guess exactly how much water is in the jug unless you fill it all the way up. Ignore the water and the jugs for a moment if you are still stuck. How can you add or subtract 3's and 5's to get to 4? This is really all you are doing; the numbers just happen to represent gallons. Adding water or dumping it out is really just addition and subtraction.
Question: What is a summary of what this article is about?
Determine where you will keep the 4 gallons of water. Know that, like all good riddles, you have everything you need for a solution. Realize that this is, at heart, a simple math problem.

Problem: Article: Being friends with them may be too much, but you are going to see them or deal with them at certain points due to having a mutual friend. You may even hang out together in a small or large group. So try keeping your distance, but be friendly enough not to put your shared friend in an uncomfortable position. For example, when hanging out, keep conversations minimal, but pleasant. Consider small talk. If the other person hates you back, they may not be willing to be friendly with you. In this case, that is on them. Your mutual friend will notice and appreciate your efforts. If your friend contacts you and asks, "me and Sarah are going to see a movie, you want to come?" try going. It may be uncomfortable, but you never know what might happen. You might be able to help the situation by spending more time together. You may learn something new about that person that may help you understand why they are the way they are. You'll get a chance to see your friend and them hang out together and see if they are different around them than they are around you. You may find that spending time with them is not as awful as you thought. While you are hanging out together, it may be easy to develop an "us" vs. "them" mentality. That could be dangerous, because you will feel and then act like you are always in competition with that person. Instead, be the bigger person and resist the urge to get into a power struggle with them. Remind yourself that they might be trying to bait you into arguing or competing with them. Find an external "enemy" a object that you all agree you dislike. If you are in school, this could be a teacher or an assignment. It could also be a celebrity, or a television show. Remember why you are working hard at this in the first place, to maintain a good relationship with your friend. Arguing in front of them, while you are hanging out together will not accomplish that. Even though you hate them, make an effort to find something about them that you like. Living with that negativity will be harmful for all three of you so try to find a way around it by picking out qualities that are positive. Think about your common interests, what do you both like? Focus on what you think is their best quality and go from there. Join in on an activity with them and create common ground. While you are hanging out together you might not be able to be friends but you should at least be civil. If you are nasty, your friend may realize that they don't want to hang out with the both of you. If just you are being nasty, it could cause your friend to prefer to hand out the the other person. It's better to always be polite. Say "hello" when you see them instead of ignoring them. Make eye contact when they are speaking. Say "thank you" and "you're welcome." While you should always try and remain polite, make sure you are not allowing the other person to walk all over you. Stand up for yourself in the face of nastiness, but try not to stoop to their level or retaliate. Your needs are important important, too. If the person is calling you names you can try to ignore it, or ask them to stop. Responding maturely will show your mutual friend that you are the bigger person and are more respectful.
Summary: Try to be acquaintances or even friends with the person you dislike. Hang out together. Don't compete. Find qualities in them that you like. Be civil and polite. Stand up for yourself.

Q: Cutting your hair every 6-8 weeks doesn't actually help your hair grow, but trimming does, therefore, if you're going to the salon, you don't have to chop it all off, especially if you don't have split ends. Trimming it will help your hair look and feel all around healthy. Elastic hair ties are extremely helpful for keeping hair out of the way while playing sports, taming wild manes, and quickly pulling your hair out of your way, but they can also be rough on your hair. The elastic ties can pull on your hair strands (especially when you tie your hair back really tight), and this tight pulling can cause hair to break. Instead of tying your hair up in tight ponytails or taut buns, try using headbands, scrunchies, or bobby pins to put back your hair without causing as much damage. Deep conditioning once a week or a couple times a month is great way to sustain smooth and hydrated hair. There are many deep conditioners that you can buy at the store, but there are other homemade alternatives as well. If you're looking to add moisture and softness to your hair, you should look for deep conditioners that have cetyl, stearyl, and cetearyl. If you are trying to strengthen your hair, you should look for ingredients like keratin, amino acids, hydrolyzed proteins, and henna. When you apply your deep conditioner, you should expect to keep it on for 5-30 minutes. This gives your hair time to absorb the nutrients and hydration properties of the conditioner.
A:
Get a haircut every 6-8 weeks. Ease up on elastic hair ties. Deep condition your hair.
