Most shark attacks occur less than 100 feet from the shore. More people are killed by bee stings and lightning than by shark attacks. Worldwide about 30 people die each year from shark attacks, which means a person has a one in 300 million chance of being killed by a shark. A shark attack most often occurs when a shark mistakes a person for a seal or other animal.
The new 2010 recommended daily allowance (RDA) is 600 IU for those 1-70 years of age and pregnant or breastfeeding women, and 800 IU for those over 71 years of age. An adequate blood level of vitamin D is 20 nanograms per milliliter, which can be achieved through daily skin exposure to sunlight.
For menstruating women, the normal FSH levels during the follicular and luteal phase should range between 5 and 20 IU/L (international units per liter). Right before ovulation during the mid-cycle peak, FSH levels should be between 30 and 50 IU/L. If a woman is post-menopausal, her FSH levels will be naturally higher, at 60 IU/L or more. At about the age of 40, most women begin a new phase of life and hormone changes begin to take place in preparation for menopause. The ovaries begin to lose their ability to produce mature follicles, estrogen and progesterone.
