And this is the explanation according to the Barefoot Doctor:
"what actually happens, energetically at least, is a major disruption in the
flow of so-called 'heart protector' energy. This, if you go with the Taoist
approach, is an energetic sheath surrounding your heart, akin in Western medical
thought, to your pericardium - there to protect your heart from painful
information, as occurs when you're forced to part company permanently with
someone you love deeply."

I guess that debunks the old saying, "It's better to have loved and lost
than never to have loved at all!"
