From Wikipedia, the free encyclopedia. Shridhar Chillal (born 1938) holds the world record for the longest fingernails ever reached on a single hand, with a combined length of 909.6 centimeters (358.1 inches).

You can also try to slow your heart rate via breathing and relaxation techniques, by practicing other mind/body therapies such as biofeedback, or by taking supplemental calcium and magnesium. For women, start with 100 mg of magnesium (citrate, glycinate, or chelate) and increase the dose up to 350 mg daily.
If you're a trained athlete, your normal resting heart rate may be closer to 40 beats per minute. A lower heart rate means your heart is able to function efficiently. This is usually a sign of cardiovascular fitness. Remember, resting heart rates are measured when you aren't actively moving.
