Best Answer

Because they are one and the same. When you feel a persons pulse with the forefinger, and not the thumb, you feel each individual beat of the heart. The reason you dont use the thumb, is because you can actually feel your own heart beat as well, making the reading innacurate. The best way to read a pulse is to count the beats for a total of 15 seconds and multiply by 4.
