Is it true that when you sneeze your heart skips a beat? And that it skips a beat when you hiccup? I dont relly know which subject this would go in

I think so..because when people say bless you, it means something.. but i really don't know either. nvm  it doesn't i just looked it up to see if it was true.. its not

Explanation:

You may have heard that your heart skips a beat when you sneeze, but that's a myth. Electrical signals that control your heart rate aren't affected by the physiological changes that happen when you sneeze. But the heart may get delayed for a second or two before resuming its regular rhythm.

For most people, heart palpitations are a once-in-a-blue-moon occurrence. Others have dozens of these heart flutters a day, sometimes so strong that they feel like a heart attack. Most palpitations are caused by a harmless hiccup in the heart's rhythm.

(searched it)

i believe the answer is true

when comparing the cases, what similarities are there in the cases that suggest one person committed these murders?
