This job involves being a live-in nanny for the children, sometimes doing some light housework, and learning about a new culture in an immersive setting. While living with the host family, you should have opportunities to explore the area around you and take language classes when you're not caring for the kids. This job provides free room and board, but it doesn't give you much pocket money. Many families provide only a small allowance each week.

Jobs such as flight attendant and commercial airline pilot are great options if you want a career that gives you travel benefits and a solid salary. Working as a flight attendant gives you a work schedule of about 65-80 hours month on average, a salary of $13-50 per flight hour, and free travel benefits that extend to your and your family members. Commercial airline pilots make about $102,520 a year. After completing your private license, logging your hours, passing the required tests, and pursuing some additional certification, you can start working and traveling at the same time.

The salary for a traveling nurse can be up to $10,000 a month, depending on experience, with food and housing accommodations usually covered as well. The pay for a travel nurse is higher than a regular nurse, and the money you make is tax-free as long as you're 50 miles (80.5km) from home.

Summary: Teach English in a foreign country. Sign up for the Peace Corps. Apply to be an au pair. Choose a long-term career in aviation. Work as a travel nurse.

Arthritis is often agitated by any motions or exercises that have high levels of impact on joints. To avoid making the symptoms of arthritis worse, you should always opt for low-impact forms of exercise. Using low-impact exercises will help reduce the stress on your joints and help keep you free from pain caused by arthritis. Try walking, swimming or bicycling for low impact activities. Even some everyday activities such as gardening or yard work could count as low-impact exercise. Before you exercise or do any heavy physical activity, it can be a good idea to apply heat to warm up your joints and muscles. Warming the areas affected by arthritis will help keep them from developing the usual pain and stiffness that can accompany heavy physical activity. Try to apply gentle heat to any areas that you have arthritis to prevent it from worsening. You can use a warm towel to apply heat. Taking a warm shower can help prepare your joints for activity. Don't use anything that is painfully hot. You can apply heat for about 20 minutes. Moving to quickly or vigorously during your day or a workout can worsen the effects of arthritis. It can be helpful to keep any motions gentle, smooth and slow to avoid triggering the painful symptoms that arthritis can bring. Always take care with your movement to help limit the effects arthritis has on your life. Always warm up before a workout. Try gently moving for at least 10 minutes before exercise. Use your full range of motion when warming up. Overexertion can bring out the symptoms of arthritis and may even cause it to develop further. If you suffer from arthritis, it's a good idea to avoid getting more physical exertion than you feel capable of. Taking it easy and getting in a break when you feel tired or sore can be good ideas when trying to limit the severity of your arthritis symptoms. Stop if you feel any pain. Swelling and redness can be signs that you need to take a break or stop for the day. After heavy physical activity, it can be a good idea to apply ice to any areas that you notice symptoms of arthritis. Applying ice can help prevent inflammation and stiffness in the areas you have arthritis, reducing the symptoms that it would have otherwise. Always apply ice after heavy physical labor or exercise to help manage your arthritis symptoms and prevent them from worsening. Try applying ice directly to areas that you have arthritis symptoms. Never apply ice directly to the skin. Always wrap ice up in a cloth before using it on your joints. Try to ice affected areas for around 20 minutes.

Summary: Avoid high impact exercise or motions. Apply heat to your joints. Move slowly and gently. Don't overdo exercises. Apply ice after exercise.

Pi, it turns out, also has a place in an interesting thought experiment called Buffon's Needle Problem, which seeks to determine the likelihood that randomly tossed uniform elongated objects will land either between or crossing a series of parallel lines on the floor. It turns out that if the distance between the lines is the same as the length of the tossed objects, the number of times the objects land across the lines out of a large number of throws can be used to calculate pi. Check out the above WikiHow article link for a fun breakdown of this experiment using thrown food. Scientists and mathematicians have not figured out a way to calculate pi exactly, since they have not been able to find a material so thin that it will work to find exact calculations.
Summary: Try this experiment to calculate pi by throwing hotdogs.
