Impact of cell phone usage on our health

Till today I not heard any case which tells me that any one get unhealthy by using mobile phone so how can we say its put impact on our health

ITS REALLY AMZING HOW THE TECHNOLOGY HAS BEING IMPROVED FROM CARDLESS PHONE TO MOBILE PHONE. But there are lot of advantages wid cell phone,which are especially useful in emergency situations..However,technology improves convenience often ha a destructuve side.Cell phone are no exception.The main healthy probelems involves like effecting the ear drum if u talk continuously an average of 2-3 hrs and the uv rays and electro-magnetic radiations due to vibrations and radiation will effect the brain directly and the vibrations which are from mobiles sometime causes cancer and also these cell phones also effects the environment due to the irradiation emitted by it.i.e.,if neil armstrong is still alive and taken this phone to moon it will become a single source of microwave radiation impacting the earth at that time next to the sun.today the amount of microwaves in earth more than in hte sun causes the environmental sick... may be in around 2020 there will be slogns like: USE CELLPHONE ONLY EMERGENCY ONE MOBILE FOR ONE FAMILY

well i dont beleive that the usage that i do on my mobile phone is affecting my phone in any shape or form. I suppose if i spent all day on my mobile ringing and texting people it would be a different matter but i wouldnt imagine it would be extremely unhealthy.
