And then, at the other end of life and the other end of the romance spectrum, comes this story:

Daughter of couple found dead in west Houston home says father died from a broken heart

From the looks of it, based solely on this one article, it looks like 92-year-old Marie died while getting dressed (my guess… heart attack). Her husband, 86-year-old Robert died very shortly thereafter. As no signs of trauma were found, it kinda sounds like he just sat down and died.

After 64 years of marriage… I guess that’s as good as it gets.

Carbon monoxide poisoning would, I imagine, also explain it…
