Are you reading this on a computer? A tablet? A cellphone? Is the device using WiFi? Perhaps you have music playing through a wireless headset? Where is your cellphone right now? Is it on you? Do you carry it in your pocket all day? On a clip on your belt? How often do you have it on the table next to you? When is the last time you picked it up? Did you just reach for it? Did you think about it? Did you fall asleep last night with it next to you? Do you use it as an alarm in the morning? When is the last time you did not have it next to you? In the same room as you?
