It means you are not dead
Your arteries have become self aware and are attempting to break free of their environment to take up a life of caporal independence.
It means you are ALIVE..! we have pulse points all over out bodies!
You need to gain some weight ;)
You're in perfect neurological health
It means that you are not one of us on this planet...you are cleared for takeoff after you fix your spaceship...God speed to you...
Must be...I can't do what he can do...
No I can't see my pulse but sometimes I can hear it.
