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.
It differs, depending on what age the kid learns all of their letters and sounds. Some kids can read at 3 or 4 years old...if their parents teach the phonics. My guess though is that most kids learn at about 5 or 6...right after Kindergarten.But this is just an estimate lol...my son is not that old yet! :P.any four year olds can recognize several words and a few are reading books on their own. (My oldest was an early reader like this.) Others may not start putting together words until 5 or 6 years of age. Most children can read simple books by about 6-7 years of age. momma2mingbu Â· 8 years ago.
