There was a time in my life that it was a strong "5". But I have to say time and age change many things. Now it is somewhere between "1" and "2". I still feel as passionate about my "Boys" but life has a way of teaching you that there are many more things more important than a cowboys win. JMO
Bingo.
I now give myself twelve hours to get over it, if needed. As you said, life will surely help put things in perspective. In particular, having kids. At the end of the day, it's entertainment and i've learned to accept it as such. Doesn't mean i don't follow the team as closely as before because i do.
So to answer the OP's question - the success of the Cowboys is surely a big deal, but I'd say they now have zero effect on my week.
Not to mention, the spectacular late game collapses over the past decade have to an extent numbed me to disappointment.I don't have to name the games. If you're a fan, you've seen them and know what im talking about.
