To Fight or Not To Fight

I was going to write a pithy little post about how I was arguing with Heather last night on whether we should fight more in light of the recently reported findings that couple who fight live longer.

Spouses Who Fight Live Longer
A good argument with your spouse could be just what the doctor ordered.

Preliminary results from a survey of married couples suggest that disputing husbands and wives who hold in their anger die earlier than expressive couples.

But while finding the article on LiveScience so I could link to it, I found this other article on LiveScience from March 2006

Marital Spats Raise Risk of Heart Attack
Fighting with the one you love can leave you broken-hearted, a feeling that now appears to be more than just figurative.

Marital spats and dominating behavior are related to hardening of the coronary arteries, which supply blood to the heart. Clogged arteries raise the risk of a heart attack.

So now I don't know what to do.

How does confusion affect longevity?
