One of the most surprising things about the black colored pair of eyes is that true black eyes are very rare. What we see and call as black eyes are in actuality just very dark brown eyes. The dark brown or black, as we may call it for own usage is often associated with night, mystery and intuition.
There are different ways to calculate your target heart rate zone, but the Karvonen Method is one of the most effective because it factors in your resting heart rate. Here's how to calculate your target heart rate zone using the Karvonen Method: 1. Measure your resting heart rate when you first wake up. You can do this by taking your pulse for one minute while still in bed. To take your pulse, place two fingertips (not a thumb) on either the radial (on your wrist, at the base of your thumb) or carotid (neck, next to your larynx) pulse site.
How It Is Done. You can measure your pulse rate anywhere an artery comes close to the skin, such as in your wrist or neck, temple area, groin, behind the knee, or top of your foot. You can easily check your pulse on the inside of your wrist, below your thumb. 1  Gently place 2 fingers of your other hand on this artery.2  Do not use your thumb because it has its own pulse that you may feel. 3  Count the beats for 30 seconds; then double the result to get the number of beats per minute.our pulse is the rate at which your heart beats. Your pulse is usually called your heart rate, which is the number of times your heart beats each minute (bpm).
