Tracking People Using Computer Chips

The question posed is basically whether or not i believe it is ethical to track young children, teenagers, or forgetful senior citizens using computer chips that would be put into their body. I do not believe it is ethical to to use tracking devices on people simply because of freedom. I understand that worrying parents might want to track their young children but why do you have to put a computer chip in your child who is under the age of five. In my opinion a good parent would never lose track of their children and when they are in situations where i couldnt be present (such as pre-school) you simply have to trust people to take care of your children the same way that my parents trusted other people to take care of me. I understand why people want to track young children but i think it would be extremely unfair to track a teenager or a senior citizen. Teenagers need their space and freedom and if anything i believe if they knew you organized a way to track them you could potentially lose all of their trust and respect. Most teenagers are rebellious but i personally do not believe that putting a micro chip in their skin will stop them from doing anything. If a parent truly feels the need to track their children they can set up tracking devises on their cell phones and we all know that teenagers cant live without their cellphone. With senior citizens i just don't believe that we should be aloud to chose whether or not a tracking devise could be put into them. They are adults and have been their whole lives and sometimes we just need to believe they can take care of themselves and if they can't take care of themselves there are places they can live and be taken care of but still i see no use in putting a monitoring system on them. I would not be supportive of an act to require children to have I.D. chips in them for all the reasons i have stated above. Kids had to grow up in the forties and fifties and they were never tracked and their were no issues back then so i dont see why we need to cross a line simply to have more peace of mind.
