If you need to remember something, you probably have a strategy or two to decrease your odds of forgetting. Many people like to write things down. Some believe that even if they never look back at their notes, they'll still be more likely to remember what they wrote simply by completing that exercise. And they may be right. But if you really want to increase your chances of remembering something, there's something better you can do once you pick up that pencil and notepad.

If you aren't in good health as you age, you may find that your bones are getting weaker while your blood vessels are getting harder. In fact, the cells forming your arterial lining (called endothelial cells) may actually be turning into osteoblasts, cells that aid in the formation of bone.

Remember when you were young and the last thing you remembered when you woke up was right before you went to sleep? You were unconscious the entire night. No rolling over in bed to get comfortable. No getting up to go to the bathroom. No waking up from every little noise. Just pure, unadulterated sleep. How good was that!
