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 To Measure Your Pulse. 1  Turn the palm side of your hand facing up. 2  Place your index and middle fingers of your opposite hand on your wrist, approximately 1 inch below the base of your hand. 3  Press your fingers down in the grove between your middle tendons and your outside bone. You should feel a throbbing - your pulse. Count the number of beats for 10 seconds, then multiply this number by 6. This will give you your heat rate for a minute. Example: If you count 12 beats in the span of 10 seconds, multiply 12 X 6 = 72. This means your Heart Rate or pulse, is 72 (or 72 beats per minute). Another popular way to measure pulse rate is by measuring it at the neck (carotid pulse). This is especially convenient during exercise.
