Worn joints. Just like the other joints in your body, your neck joints tend to wear down with age. Osteoarthritis causes the cushions (cartilage) between your bones (vertebrae) to deteriorate. Your body then forms bone spurs that affect joint motion and cause pain.
As the user guide explains, kids hardly read (and you canât expect a 3 year old to read!). So you get games which teach you about letters and numbers starting from the real simple ones to others that teach more fundamental things like reading time or guessing colors.
Teach a child to read who is as young as four. Children as young as four who have not yet learned to identify letters or use a mouse and keyboard can learn to read using this program. More advanced readers can use the program to move quickly to a third grade reading and writing level.
