    Grab a stopwatch, or a clock or watch with a second hand,
then find your pulse. You can locate your pulse either in your
radial artery on your wrist or at your carotid artery in your
neck. Choose the spot that works best for you.   The only trick
to measuring your heart rate is that you must use the correct
fingers to do the measuring. Your thumb has a light pulse and
can create some confusion when you are counting your beats. It's
best to use your index finger and middle finger together.  After
you find the beat, you need to count how many beats occur within
60 seconds. The shortcut to this method is to count the number
of beats in 10 seconds, and then to multiply that number by 6.
This method gives you a 60-second count.  Example: You count 7
beats in 10 seconds: 7 x 6 = 42 beats per minute.   If you have
trouble finding your pulse or separating the beats in your body
from the ticks of your watch, ask a friend for help. Have your
friend count your pulse beats while you watch the clock or vice
versa.
