Motion sickness
People who suffer from motion sickness usually experience symptoms when they are in a moving vehicle (car, plane, or boat), but symptoms may also occur while watching a movie or playing a video game.


Lyme Disease

For ticks to develop, they must feed on animal or human blood. Their bites are usually painless and often go unnoticed. Before feeding, an adult tick measures between 1 and 3 millimetres, but can triple in volume when filled with blood, reaching the size of an apple seed. Ticks that have not reached adulthood are known as nymphs, and can also transmit Lyme disease. At the nymph stage, they are very small and because they remain virtually undetected, they are able to stay attached to skin longer. Generally speaking, an infected tick must be attached to skin for 36 to 48 hours or more before it can transmit the disease to a human. Ticks do not jump or fly. They are normally found in forests, woods, tall grasses and piles of dead leaves. Ticks that transmit Lyme disease are found throughout Canada, the United States and in other countries.
