Let’s play a game!

Why did my heart rate spike by 20bpm (from 106bpm to 126bpm) when standing to make an iced coffee this morning?

Was it:

A) I laughed at something my cat was doing;

B) I dropped the iced coffee lid and had to pick it up; or

C) I sneezed

Place your best guess and tell me how silly things result your heart rate increasing!
