Most male fin and blue whales sing at around 17 to 18 hertz, which is too deep for humans to hear, but the 'lonely' whale communicates at 52 hertz. When more recordings were released in the nineties, Dr Watkins studied the 52 hertz whale more closely.
The average person needs to absorb just a small amount of iron each day to stay healthy (around 1 mg for adult males and 1.5 mg for menstruating females). To achieve this, however, we need to consume several times that amount. This is because our bodies absorb only a fraction of the iron contained in the foods we eat.
Depending on the severity of your anemia, as well as your age and weight, your doctor will recommend a dosage of 60 - 200 mg of elemental iron per day. This means taking one iron pill 2 - 3 time during the day. Make sure your doctor explains to you how many pills you should take in a day and when you should take them.
