Reading has a host of benefits - tangible and intangible and should in fact become a habit as common as bathing or eating.
1. Reading can make us Smarter
Reading is a very active state exercise for our mind as opposed to watching TV or listening to music. Reading forces our brain cells to engage in activity as we paint a vivid image in our mind about the story that we are reading.
Our brain is also a muscle which must be worked on a regular basis as this will keep our mental faculties constantly engaged and thus keep us sharper and smarter.
