The Candle Burning Guide - Center Burning Candles. Certain candles are designed to burn down the middle for different reasons, or a combination of different reasons. Candles with a unique finish, or unique burning characteristic, may burn down the middle in order to position the flame inside of the candle and illuminate from the inside out.
To find your maximum heart rate, subtract your age from 220. For example, if you are 40 years old, your maximum heart rate is 180 (that is, 220 - 40 = 180). Multiplying this by 50 percent and then 85 percent results in your target heart rate range of 90 to 153 beats per minute.
A normal resting heart rate is usually 60-100 beats per minute. Your number may vary. Children tend to have higher resting heart rates than adults. The maximum heart rate is, on average, the highest your pulse can get. To calculate your predicted maximum heart rate, use this formula: 220 - Your Age = Predicted Maximum Heart Rate. For example, a 40-year-old's predicted maximum heart rate is about 180 beats per minute. Your actual maximum heart rate can be determined by a graded exercise test.
