This cool write up of yours has left me wondering if truly technology is doing more good than harm. Aside the radiation coming out of them, an average individual tends to spend more than 12hrs a day with their phones especially the smart ones. I can testify to this myself because am also a victim to this life style especially when out of work. With this long time spent with them, I bet tendency of exposure is very high. I guess I'll have to reduce the time spent with this gadget thanks to informative article.
