 Good morning everyone, my name is Robert and this is Step. Today we are going to talk about something we are all familiar with, smartphones. What do you think of when you see this? Smartphones are bad for you. That's what many people think but we are not so sure. That's right, so we are going to talk today about the impact of smartphones on human health. I am going to give you some brief background on the issue and explain the negative impacts of smartphones on our health. Then I will bring up some of the positive impacts that smartphones have had on human health since they were invented. After that, I will give you a quick summary of our findings and we will answer any questions you may have on the issues.
