. The act of breathing supplies oxygen to your entire body. Breathing deeply uses the entire capacity of your lungs to oxygenate blood. Though normal breathing levels aren't unhealthy, deep breathing reaches the peak level of oxygen flowing through your body. Pay special attention to your diaphragm while slowly inhaling and exhaling full deep breaths. Feel your diaphragm lowering while you inhale and exhale fully until you feel your stomach muscles tighten and your diaphragm lift. Like deep breathing, laughing forces more air out of your lungs, which leads to a greater inhalation of fresh air and a higher supply of oxygenated blood. Laughing also works abdominal muscles and increases lung capacity. Aerobic exercise doesn't necessarily make your lungs stronger on its own. However, great cardio-respiratory fitness makes it easier for your lungs to supply your heart and muscles with oxygen. This puts less strain on your lungs, allowing them to function properly with less work. The American Heart Association recommends at least thirty minutes of moderate-intensity cardio exercise five days a week or more in order to maintain good cardiovascular health. Studies have shown that diets rich in fresh fruit and fish are associated with benefits to lung health. This is especially the case with those who experience asthma, COPD, and other common lung diseases. A 2010 study also showed that a diet rich in cruciferous vegetables (broccoli, cauliflower, cabbage, kale, bok choy) can decrease the risk of lung cancer. The hairs in your nose act as a filter and only let extremely fine particles through. Your nose can filter particles as small as a single grain of pollen with 100 percent efficiency. This makes breathing through your nose a much better option than breathing through your mouth. Sickness, allergies, and other conditions can all lead to common nasal congestion. A plugged nose means you're pulling 100 percent of germs and pollution directly into your lungs by breathing through your mouth. This can exacerbate conditions such as asthma and other lung complications or even cause them in those who don't already suffer from them. Treat common allergies with antihistamines or other decongestants to help keep your nose clear. Additionally, overly dry nasal passages that can accompany sickness make nose hairs less effective at filtering air. Consider using a humidifier or even an over-the-counter nasal mist to keep your nasal passage moist and properly filtering the air you breathe. In addition to its myriad other positive effects, drinking plenty of water is good for your lungs. You lungs have a mucosal lining, and staying hydrated keep the lining thin, which helps your lungs function more efficiently. If you have asthma or another respiratory condition, ensure you see your doctor for regular exams to help control the condition. Albuterol, a prescription bronchodilator, works well to help with asthma symptoms, for instance. Yearly flu vaccines and pneumococcal vaccinations can help lower the risk of respiratory infections. This also means less risk of developing associated lung complications such as pneumonia. Smokers between the ages of 19 and 65 should get a pneumococcus vaccination. Also, anyone with chronic heart disease, chronic lung disease, alcoholism, chronic liver disease, or who is over the age of 65 should get the pneumococcus vaccination.

. Financial discipline is a vital aspect of financial independence. The ultimate goal is living within your financial means, both short- and long-term. Pay attention to the ways you're spending money. Perhaps the most important aspect of preparing yourself to become financially independent is ensuring that you are not spending more than you're making. Fortunately, there are several methods to track your spending: Use a ledger or a spreadsheet. The manual approach is great way to start, as it makes you keenly aware of every expense. Whatever you use, the act of entering every expense into a database of your expenses will keep you better informed of your own spending patterns. Use free accounting software. Once you have multiple bank accounts, and different types of income and expenditures, your ability to organize the corresponding information may demand more than your spreadsheet skills can handle. Online platforms such as Personal Capital and Mint are free and immensely helpful. For more specific advice, see How to Manage Your Money Wisely. With an eye towards making immediate improvements in your financial behavior, evaluate how you spend most of your money. There are everyday expenses many people often overlook that can hamper your ability to live within your financial means. Because a handful of expenses consume most of your budget, pursue these first and minimize common types of spending. Minimize rent or mortgage payments. Choose your home based on the cost of living in the area. Go for as little home as you're comfortable in both when buying or renting. Consider purchasing a duplex and renting out one side or renting out rooms in your home. Reduce your reliance on vehicles. Vehicles not only diminish the quality of our environment, they are also associated with substantial financial costs. Walking, biking, and taking the bus will reduce your spending immediately. Clothing, food, and leisure are areas in which many people spend far more than is appropriate, given their income. Remember that even everyday decisions regarding your method of transportation or eating habits can be the difference between overspending and being able to begin saving for financial independence. Buy what you can used. Thrift stores and craigslist offer high quality items for only a fraction of what they would cost new. Do it yourself. From home repair to vegetable gardening, you can save money (and increase your worldly wisdom) by taking matters into your own hands. There's also an undeniable sense of satisfaction fixing something yourself or growing the ingredients to make yourself a salad from your own yard. Understand that debt does not necessarily prevent you from becoming financially independent. Also recognize that you don't need to pay it off as quickly as possible. Pay off debt steadily, but within your ability to do so while achieving financial stability. Most importantly, do not take on unnecessary debts. When paying off debt, start with high-interest debt, like credit cards and auto loans, before paying off student loans. Don't take on new debt. Your education is a reasonable expense to take out loans for, as it is an investment in yourself. Even a car loan can be justifiable if it is the only way you can afford to buy a vehicle. Continually increasingly credit card debt, however, is blatantly irresponsible. Not only is taking on new debt a clear sign that you are not living within your means, continually acquiring debt will ensure that you are unable to achieve financial independence. Never finance a vacation, new clothes, or even unnecessary food purchases with a credit card. A good rule to follow: only take on debt for investments, not for lifestyle.
