Yeah, there's time leakage, but not as much as you make it out to be.
Up at 4:30, ok, I hit snooze for 10 minutes once. I then sit and drink some coffee and look at hacker news. 15 minutes or so. I shave (my head too, I'm a baldy), do my morning business, and shower. That's about 20 minutes. I usually have some dishes from the night before that need cleaning, or a dishwasher that I empty.
Like I said, I could work during Movie time, but you know what, I love my wife and enjoy spending time with her. I also have other hobbies (seems you mentioned above that your work is your only hobby)
I also notice some of the other wifes don't work and take care of the house and kids. My wife works full time, and I'm a good husband that does my share around the house and and equal share raising the kid. Sure, I could push more on her and be selfish, but I'm not going to.
My only real time leakage is in the mornings (I like and feel I need time to wake up) and on Friday with a weekly movie. I don't really care that you think it's odd. 2 hours a week watching "TV" is so minimal people I know call me a freak. The fact that it seems alien to you to set aside time to relax and not think about anything says volumes about you (not necessarily bad things, mind you).
Thanks for the link. Looks a little, uh, suspect. My wife is a Physical Therapist though, I'll run it by her.
Edit: Link might not be relevant for me, only been doing OT for a couple months, before that had an EMG done and nerve damage was shown to exist.
