Spinach is good for health
It is rich in antioxidants both betacarotene and lutein. Although the actual amount is relatively small, spinach contains far more of the two combined than most other fruits or vegetables. Antioxidants help fight formation of free radicals which are highly reactive molecules that can damage DNA and are responsible for the development of certain diseases.

Researchers have found that regular, moderate exercise may prevent impotence. Men who burned at least 200 calories a day through exercise were less likely than inactive men to become impotent.

Men with strong grips are less likely to develop disabilities in old age. A firm handshake may make a good first impression, but its real importance might not be felt for years. A study found that middle-aged men with strong grips are less likely to develop disabilities in old age. Good muscle strength in middle age can give people a margin of safety in later years, when they may face long periods of inactivity after surgery or illness, the researchers said in Journal of the American Medical Association. At the final exam, researchers timed the men's walking speed and checked their ability to rise from a chair. The one-third with the weakest grips at midlife were twice as likely to have problems caring for themselves as those in the upper third.

Common findings in Parkinsonism and Alzheimer's diseases. There is compelling evidence indicating common clinical and pathological findings in idiopathic Parkinsonism and Alzheimer's disease and Amyotrophic Lateral Sclerosis. These conditions develop from pathological processes with more similarity than diversity. It is now known that if Alzheimer patients servive long enough, many would develop parkinsonian features, and if PD patients servive long enough, more often than not, they get demented features.
