Signs of Lyme disease include skin rash and painful inflammation of joints (particularly the knees), accompanied by flu-like symptoms. The symptoms of Lyme disease increase in severity as the disease spreads though the body. Early diagnosis and treatment are important to stop the progression of the disease. If untreated, the disease can result in neurological disorders such as peripheral neuropathy, including Bellâs palsy, as well as pain, numbness or weakness in the limbs.

Commercial jets are by far one of the fastest ways to travel. Each type of jet has its own takeoff, cruising and landing speed. A commercial jetliner usually takes off between 160 and 180 mph. The varying speed can be due to wind resistance, overall weight capacity and/or the use of high-lift devices. Airspeed is measured with respect to the velocity of the object through the air. The average cruising speed is between 550 and 580 mph. Wind resistance is a key factor when determining the speed of the aircraft. The average landing speed for a commercial jet is 150 to 166 mph. Changes in speed can be a result of weather conditions, runway length and landing weight.
