Bits and Pieces

For a Healthy Brain, Physical Exercise Trumps a Mental Workout.
Regular physical exercise appears to protect the brain from shrinking, a natural occurrence in aging that is associated with memory and thinking problems. This relatively large brain-imaging study, which included brain scans using magnetic resonance imaging (MRI), 
involved more than 600 people in Scotland between the ages 70 and 73. The researchers found a strong and direct correlation revealing that as physical exercise increases, brain shrinkage decreases. The study discussed the need for both “physical exercise and non-physical leisure and social pursuits”.  All have so many benefits, however for preventing chronic diseases; combating depression, fatigue and also apparently brain shrinkage there's no harm in pursuing exercise at any age. See, there are ways to prevent shrinkage. Source: LiveScience.com
 
Two keys to strong bones: Calcium and Vitamin D
Although bone-weakening osteoporosis is quite common among older people, it is not an inevitable part of aging. The best insurance against osteoporosis is building the highest bone density possible by your 30s and minimizing bone loss after that; but if you’re already in midlife or beyond, there is still much you can do to preserve the bone you have and perhaps even to replace lost bone. Daily weight-bearing exercise is the best medicine. Getting enough calcium and vitamin D are two other critical strategies for keeping bones strong. 
 
How much Calcium do you need? The recommended daily intake for calcium is 1,000 milligrams (mg) a day for adults up through age 50 and 1,200 mg a day for people ages 51 and older. In building bone, calcium has an indispensable assistant: vitamin D. This vitamin helps the body absorb calcium, and some researchers think that increasing vitamin D can help prevent osteoporosis. Vitamin D fortified milk and yogurt, as well as eggs and some breakfast cereals, are all good sources.  Five to thirty minutes of sunlight a couple of times a week 
will also help enable you to make enough of the vitamin. If you have fair skin, less exposure time may be necessary.       Source: Harvard Medical School
 
Foods that fight fatigue
Having a well balanced diet consisting of unrefined carbohydrates, proteins, and fats, with an emphasis on vegetables, whole grains, and healthy oils, will help keep you healthy and keep your body running smoothly and feeling good. 
 
Other Tips:
•Candy and other simple sugars give you a quick burst of energy, but that boost fades quickly and can leave you feeling depleted 
 
and wanting to eat more.
•Eating small meals and snacks every few hours throughout the day provides a steady supply of nutrients to body and brain.
•Researchers have observed that people who have a big lunch typically show a more pronounced afternoon slump. One possible explanation is a sharp rise in blood sugar after eating, followed by an energy dip a few hours later.
•It doesn't take much to feed your brain and pep you up a bit; a piece of fruit with few nuts can do the job.
