Being a nerd is good. Habit of reading books will increase knowledge and increase our thinking ability. Not only nonfiction books that can educate you, but fiction books also have the same benefits as non-fiction books. But there is a tendency to be paid a bookworm, namely: Cause the eye minus (miopi), or even eye plus (hipermetropi). Miopia and hipermetropy are eye damage caused by a lack of elasticity of the silaris muscle in the eye. This silaris muscle is the focus of the eye.

When we do book reading activities, our muscles may be required to remain in static condition.

Because it is in a static condition that is too long, then the silaris muscle becomes inflexible again. In the end, the sufferers of myopia and hipermetropi can not see maximally the object that is too close or too far away. Not only that, a nerd also usually has a problem in posture. Because it's too cool to read a book, sometimes a nerd sitting with an imperfect position or may forget to use a worsening posture.

Not only the posture, fitness and endurance of a nerd also continues to deteriorate over time. Then, because it's too cool to read a book, usually a nerd forgot to socialize. This causes a bookworm does not have many friends despite his wide insight. Lastly. Reading books can indeed cause dementia, but knowing many books of a different kind at a time will actually cause a person to lose memory because of the 'overlapping' configuration of information in the brain.
