But, the TV can always be turned off. No sunk cost there, in fact, I've gained hours and hours on the weekend. Went for a walk in the park with Mrs WBill last Sunday, while WBill Jr rode his bike all over the place. Way more fun than sitting on my butt in front of the TV.
I started moving away from the NFL last season and have cut it off completely this year. I've been surprised at how little I miss it.
