Is that Harm?

they say. this is not so far off what they used to say about televisions.

any electronic gadget that emits waves for signal can cause harm especially if it is being used excessively. Though there are standards for these signals being followed by manufacturers, sometimes it is being abused because of our lifestyle. Whether we use it or not, we are already exposed to a lot of these harmful signals so what we can do is just use it the proper way.. there are actually test made by some people about it and i do believe them. Its just a matter of being responsible for our things to lessen its harm.

I have heard rumors about it but am not sure.

yes...it is harmful brain if you speak for a long time.....the radio signals affect the brain cells,especially when you are not talking with a headphones and microphone and it affects the most when the battery is low(coz cell phones pump up more signals at low batteries)..but bluetooth headphones also affect the brain coz bluetooth waves are capable of causing tumour when exposed for a long time....cell phones surely affect brain....but regarding heart ....no problem with it
