These seem like perfect Valentine's Day stories, so I'll mention them now instead:

Lost love really can cause broken heart

Confirming the wisdom of the poets and philosophers, doctors say the sudden death of a loved one really can cause a broken heart.

In fact, they have dubbed the condition "broken heart syndrome."

In a study published just in time for Valentine's Day -- February 14 -- doctors reported how a tragic or shocking event can stun the heart and produce classic heart attack-like symptoms, including chest pain, shortness of breath and fluid in the lungs.

Unrequited love can be a 'killer'

Lovesickness can kill and should be taken more seriously as a legitimate diagnosis, according to health experts.

Frank Tallis, a clinical psychologist in London, is among those calling for greater awareness of the "illness" in a report in The Psychologist magazine.

He said many are "destabilised by falling in love, or suffer on account of their love being unrequited" and this could lead to a suicide attempt.

Few studies deal with the "specific problem of lovesickness", he said

Is anyone really surprised by this?

These may be the most unnewsworthy Valentine's Day-timed stories to be ever done. Well, except for stuff on chocolate.
