Children Should not be Allowed to Own Smart Phones Until They are in Their Mid Teens (15-16 y/o)

I start my argument. Best of luck to my respectable opponent :)Health HazardsIn today's times, many parents give even their toddlers tablets and smart phones to play with. Now how could these young ones be expected not to be addicted to something even a mature adult gets addicted to? "An interesting experiment conducted by researchers at the Center for Toddler Development at Barnard College, showed that children between 18 to 36 months old, when given an iPad to play with, were so absorbed, that they did not respond to their names." Smart phones cause addiction at any age, the difference lies in the level of maturity of the person. Now the person might become mature at an age earlier than 15, or not become mentally mature even after crossing 20, but the age 15-16 years has been selected by me as an average for when most people tend to become more responsible, i.e. more mature. AGE 0-5 y/o (toddlers and young kids (brain is in developing phase))If smart phones become an addiction at an early age, they do more harm than good. Radiations being at number one. When you are giving that innocent toddler a smart phone, you are actually giving him/her a radiation emitting box of terror. A child's brain tissues are more absorbent than an adult's, meaning that the radiations will do more harm to the young kids. Bone marrow of an average child absorbs 10X more radiation than an adult's. And as anyone would know, radiations come with a chance of causing diseases such as cancer.Brain development is negatively affected.Substituting physical activities and human interactions with smart phones would never do good, according to the common sense of a sane person. The young kids' brains are developing, they will obviously develop better if they face the physical world themselves, by using their own senses.The counter argument for this is that their are educational games for the kids, but the use of mobile devices in particular online games should support imaginative play instead of trying to use them as a way to keep children busy, which is normally the case.AGE 5-10 y/o ( young students)Hindrance to concentration and focus.Most people, CAN NOT multitask. Switching between two tasks is something that takes up a lot of energy, especially when the task which needs to be switched from is an addiction. A simple 'ding' for a message can and does shift focus of people (more of kids than adults). An average kid will, after checking the message, engage in online chats, games, etc. for the so called '5 minutes'(which ultimately turn out to be hours) before they realise they have not completed the project they had to submit the next day or did not study for the big test the next day. Though, the only difference this causes is that now they kill time by chatting and playing the games while stressing about what will happen the next day, instead of killing time with a calm mind which they were doing earlier.Reduced social skills and face to face interaction.Have you ever read about people who do terrible in interviews and get rejected? Funny stories, eh? This happens mainly because of lack of social skills. And guess what smart phones help in building ? THE LACK OF SOCIAL SKILLS.The age 5 - 10 involves stuff like brain development, learning social skills, learning important values amongst family and friends, starting to know which field best matches with your interests (Do you love learning? Are you good in athletics? Are you an all rounder?) And again guess what smart phones do? STOP ALL OF THIS IMPORTANT BUSINESS FROM HAPPENING IN THE NATURAL WAY!AGE 10 - 15 ('Tweenagers') Apart from the health problems and lack in social skills, the problems which prevail more in this age group are things like increased 'FOMO' (Fear of missing out), sleep disruption, procrastination and increased stress (I had a smart phone for a week when I was in my 'tweens' and I gave it back myself, because I noticed, IN JUST ONE WEEK, how my life was being affected in a bad way from it!) The tweenagers have hormonal changes taking place in them. They are naturally more irritable and irrational. Sleeplessness, procrastination, stress DOES NOT help, believe me, rather, these just help to make them more irritable. Moreover, these kids are more likely to be opened up to things they should not be watching or doing (pornography, etc.). They thus waste an important part of life on worthless activities. Now, the reason most kids get smart phones is because of safety reasons, to be always connected with the parents. But a simple cell phone does exactly the same, help ensure safety without a myriad of disadvantages which a smart phone poses. Till the age of 15 though, most people have developed to become responsible and have the important values hard wired within. Now they are ready to handle the otherwise 'poisoned chalice' to gain more advantages than the inevitable disadvantages. *SOURCES WILL BE MENTIONED IN LAST ROUND*
