Like Chris I also watch 8-12 hours a day thought that goes up to around 18 or more on days off. I am also w/o a TV connection so my use is mostly targeted disc and internet. I do listen to random music I’ve ripped off internet radio for new bands I might like.
Same here on the sleep around 6 hours or less. Another thing on sleep is supposedly you sleep less as you get older which seems to be the case for me. However, about once a week I do sleep around 10 hours. It’s the night after I do my long run so my body is wasted.
I can say w/o a doubt I’m getting my monies worth from my HT system.
