Regular exercise will almost always increase their energy level. The more energy that you use, the more energy you will have. It has now been proven that exercise will make you live longer. Some individuals at high risk for heart disease should have a stress test before starting an exercise program. Some physicians recommend a stress test if you are over 45 years old or if you are over 35 and have risk factors for heart disease.
Exercise also helps prevent osteoporosis.
Many experts now recommend that all females take estrogen after menopause. This helps prevent osteoporosis and, if taken in conjunction with progesterone, also may prevent cancer of the endometrium or uterus. It is also important to take approximately 1200 mg. of calcium every day. This is important even in young females. Evidence suggests that you are more likely to prevent osteoporosis if you have an adequate calcium intake starting in the 20's.
