To think that there I was, opening the door, little by little, and he not even to dream of my secret deeds or thoughts. I could scarcely contain my feelings of triumph. Never before that night had I felt the extent of my own powers - of my sagacity. A watch’s minute hand moves more quickly than did mine. Upon the eighth night I was more than usually cautious in opening the door. So you see he would have been a very profound old man, indeed, to suspect that every night, just at twelve, I looked in upon him while he slept. And every morning, when the day broke, I went boldly into the chamber, and spoke courageously to him, calling him by name in a hearty tone, and inquiring how he had passed the night. And this I did for seven long nights - every night just at midnight - but I found the eye always closed and so it was impossible to do the work for it was not the old man who vexed me, but his Evil Eye. Ha! - would a madman have been so wise as this? And then, when my head was well in the room, I undid the lantern cautiously - oh, so cautiously - cautiously (for the hinges creaked) - I undid it just so much that a single thin ray fell upon the vulture eye. It took me an hour to place my whole head within the opening so far that I could see him as he lay upon his bed. Oh, you would have laughed to see how cunningly I thrust it in! I moved it slowly - very, very slowly, so that I might not disturb the old man’s sleep. And every night, about midnight, I turned the latch of his door and opened it - oh, so gently! And then, when I had made an opening sufficient for my head, I put in a dark lantern, all closed, closed, so that no light shone out, and then I thrust in my head. You should have seen how wisely I proceeded - with what caution - with what foresight - with what dissimulation I went to work! I was never kinder to the old man than during the whole week before I killed him. Whenever it fell upon me, my blood ran cold and so by degrees - very gradually - I made up my mind to take the life of the old man, and thus rid myself of the eye forever. I think it was his eye! yes, it was this! One of his eyes resembled that of a vulture - a pale blue eye, with a film over it. It is impossible to say how first the idea entered my brain but once conceived, it haunted me day and night. How, then, am I mad? Hearken! and observe how healthily - how calmly I can tell you the whole story. I heard all things in the heaven and in the earth. Above all was the sense of hearing acute. True! - nervous - very, very dreadfully nervous I had been and am but why will you say that I am mad? The disease had sharpened my senses - not destroyed - not dulled them. my.clevelandclinic.Hear “The Tell-Tale Heart” read aloud. diseases-conditions/bradycardia/symptoms-causes/syc-20355474 What’s a normal resting heart rate? /healthy-lifestyle/fitness/expert-answers/heart-rate/faq-20057979 Influence diagram of physiological and environmental factors affecting heart rate variability: An extended literature overview. heart-health/want-to-check-your-heart-rate-heres-how Want to check your heart rate?

The chart below shows estimated maximum and target heart rates for various age groups: You can then use your maximum heart rate to determine what your target heart rate is while exercising. For example, if you’re 45, then your approximate maximum heart rate is 175 bpm (220 – 45 = 175). To calculate your estimated maximum heart rate, you can use the equation of subtracting your age from 220. Exercising at the higher end is ideal for building cardiovascular strength. Typically, exercising at 60 to 85 percent of your maximum heart rate is most beneficial.Įxercising at the lower end of this percentage or doing interval training (where your heart rate goes up and down) is ideal for fat burning. Target heart rates can be used to maximize the efficiency of your workouts, as well as to keep you safe. Very fit individuals such as athletes may have resting heart rates below 60 bpm. The ideal resting heart rate for adults is 60 to 100 bpm. Heart rate norms are based primarily on age rather than gender, although men tend to have slightly lower heart rates than women.
