Alternatively referred to as a cell, cellular, and cellular phone, a cell phone, which is also sometimes abbreviated as “cp” is a mobile phone or portable phone that enables a user to communicate almost anywhere in the world. The cell phone was invented by Dr. Martin Cooper who led a team of developers at Motorola and made the first cell phone call in April 3, 1973 at Motorola.

Based on Gabor Maté’s two decades of experience as a medical doctor and his groundbreaking work with the severely addicted on Vancouver’s skid row, In the Realm of Hungry Ghosts radically reenvisions this much misunderstood field by taking a holistic approach. Dr. Maté presents addiction not as a discrete phenomenon confined to an unfortunate or weakwilled few, but as a continuum that runs throughout (and perhaps underpins) our society; not a medical "condition" distinct from the lives it affects, rather the result of a complex interplay among personal history, emotional, and neurological development, brain chemistry, and the drugs (and behaviors) of addiction.

Simplifying a wide array of brain and addiction research findings from around the globe, the book avoids glib self-help remedies, instead promoting a thorough and compassionate self-understanding as the first key to healing and wellness. In the Realm of Hungry Ghosts argues persuasively against contemporary health, social, and criminal justice policies toward addiction and those impacted by it. The mix of personal stories—including the author’s candid discussion of his own "high-status" addictive tendencies—and science with positive solutions makes the book equally useful for lay readers and professionals.

There is an enormous impact of the mobile phone on contemporary society from a social scientific perspective. In the book Perpetual contact: mobile communication, private talk, public performance the author James E. Katz, PhD, writes: "They have transformed social practices and changed the way we do business, yet surprisingly we have little perception on their effect in our lives." (Katz, 2002)

In a survey made by Gazelle, “More than 25% of respondents reported that they “almost always” use their iPhone while in a social setting such as during a meal or during a party. In addition, 58% said they use it ‘usually’ or ‘occasionally’ during these settings. Not owning a cell phone is definitely the exception rather than the rule in this day and age. It’s rare to see someone leave home without their cell phone, even though 20 years ago everyone managed just fine without them.

The prevalence of cell phone dependency has been alarming for years now, but it’s become even worse recently with the introduction of smart phones. These phones let you do just about anything – make calls, text, browse the web, play music, watch videos, send and receive emails, take pictures, lookup directions to anywhere in the world, check the weather forecast, choose from hundreds of different games, and more.

There’s nothing wrong with owning and enjoying a cell phone, but it becomes problematic when cell phone usage interferes with your day-to-day activities and relationships. Mobile phones are used for a variety of purposes, including keeping in touch with family members, conducting business, and having access to a telephone in the event of an emergency. Some people carry more than one cell phone for different purposes, such as for business and personal use.

We need cell phones to stay in touch. In this day and age we are away from home more often than not, and a cell phone is a good way for friends, relatives and businesses to get in touch with you when needed. They are also lifesavers in any emergency. Cell phones has been a basic necessity to the people nowadays. Although mobile phones of the past were considered a luxury item, there are tons of phones on the market today that you can get at low or no cost. Cell phones are built so that we can communicate to our loved ones from different parts of the world. We are now in a digital world and as we can see in our society many kinds of mobile phones were invented.

These phones are called smart phones because they work faster, multi-tasking, more applications and many more. Some people buy phones merely just because of its applications. Its more and new applications are sometimes used to get rid of boredom. Some people also use phones for their business like businessman, to contact their best clients and etc. Cell phones have been used widely for some important reasons.

The purpose of this study is to determine the influence of cellphones to humans’ lifestyle, socially, mentally, psychologically, spiritually and physically. This also aims to trace the evolution of cellphones and their impact to the lives of the users.
