I refuse to have TV in my bedroom, and my wife is upset with me over it. Bedrooms are for two things and two things only... Sex and sleep. I absolutely refuse to turn my bed into a sofa for lounging around in until I cannot keep my eyes open one second longer.
I spend about 100 nights each year in hotel rooms and find that once I turn the TV on, even if there is nothing interesting to watch, I will stay up until WAY past my natural bedtime hoping something better will come on after the current crappy shows end. It is stupid. I prefer to be sitting in a different room, because once I realize I am ready for bed, I can just get up, leave the room with the TV in it, and fall asleep with no distractions. I get plenty of good sleep at home - something I cannot do in hotels. When people try to convince me I am wrong about having a TV in my bedroom, they all admit to doing what I describe above several times each week - at which point I know I am probably right.
