Yea...heart beat rate is directly proportional to the size of bodies of different animals...coz smaller body radiates and lose much energy and thus needs much energy...hear beat rate of a bady is about 130 and women 78...for sparrow 300...for whale 15...etc
Have you noticed a baby's heart beat fast?- they have smaller bodies. Women have smaller bodies in general, compared to men, therefore their hearts beat a little bit faster.
I think men's hearts beat faster when they see a woman that is a knockout.
Only when they see me.
