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 manâs maximum heart rate, or max, at age 20 is about 200 beats per minute. If his target heart rate during exercise is between 50 to 85 percent of maximum, he would try to keep it between 100 and 170 bpm. The max at age 30 is 190 bpm and the target is 95 to 162 bpm. The max at age 40 is 180 bpm and the target is 90 to 153 bpm.
