When I was a little lad I used to always feel my heart before I went to sleep to make sure it was still ticking. Id get all worried it was slowing to a stop when I was really holding my breath cuase I was nervous and it would slow then freaking me out. My parents got pissed after night after night of running down stairs telling them I was dieing lol. Now ive moved on to much simpler tasks of freak organization.
