Stress
This is one of the negative effects of the modern technology. Technology is there since this Earth was created, so the modern technology today with gadgets, laptops, computer, smartphones will give us stress if we will allow those things to bring us and abuse ourselves.
I think this is indeed a detrimental effect for certain people ,, with the existence of high technology .. like some people who can spend time with laptop, mobile phone and other gatgets .. but they only spend time wasted without getting any results ..
