Thank you @tatjanastan for your informative post. Yes, technology kills. As, technology is becoming more and more inexpensive and easily available,we are taking it for granted and not using it properly.We should learn to use it only when,it is actually needed and we should shut I down when it is of no use, especially the ones with more radiations like WI-FI's.Children are more vulnerable to these radiations, exposure to children's may make children crippled both physically and mentally in the near past.Be aware.STOP USING IT UNNECESSARYLY FR NOW!!Thanks.
