Heartbeat, it's a lovebeat...

I hope this works, as I've never tried imbedding a .gif before.  Anyway, if you watch and concentrate on the one in the middle that moves a lot, you'll begin to feel and sort of hear the rhythm of it in your chest.  It's really cool and will work for most people so good luck.  If it doesn't work for you,  sorry...there's just something wrong with you.  

No reason.

Just because.  :-D
