Q. Do women get color blindness?
Color blindness affects about 10 percent of men, but only one percent of women.
Color blindness is the common term used to describe color vision deficiency. The term is misleading, because total color blindness that turns the world into shades of gray is rare.
The most common type of color blindness makes it difficult for people to discriminate between red and green. The next most common form of the deficiency affects the perception of blues and yellows. Those with blue-yellow blindness almost always have red-green blindness, too.
Q. How should I change my diet to get more iron? I think I’m a little anemic.
Iron deficiency anemia is the most common form of anemia. About 20 percent of women, 50 percent of pregnant women, and 3 percent of men do not have enough iron in their bodies.
If you have anemia, your blood does not carry enough oxygen to the rest of your body. The most common cause of anemia is iron deficiency.
You need iron to make hemoglobin. Hemoglobin carries the oxygen from your lungs to the rest of your body.
Q. I gave my 81-year-old brother a birthday present recently. As he opened it, a brief smile crossed his face. It was funny to me because I recalled that, when he was a kid, he would tear open presents and jump out of his skin. Does enthusiasm wane as we age?
I wouldn’t describe your brother as someone who has lost his enthusiasm. I would say he is just less excitable, mellower. There is scientific evidence that we do chill out as we get older.
Q. I’m 66 and I’m thinking of taking up a musical instrument. I hear that this will be good for my health. Is this true?
Playing a musical instrument seems to improve your health in a variety of ways.
I play the saxophone almost every day and can confirm that playing music definitely relieves stress. And stress can be bad for your mental and physical health.
There’s a lot of evidence that playing music is good for you.
According to a study published by the American Psychological Association, playing an instrument as a child keeps the mind sharper as we age.
Q. My Aunt Lillian is a total health freak. The other day she said cinnamon is good for you. Come on! Cinnamon?
Recent research indicates that cinnamon may be helpful for people with Type 2 diabetes, a chronic condition that affects the way your body processes sugar. Type 2 diabetes can be life-threatening if you don’t treat it.
One study found that cinnamon taken twice a day for 90 days improved the condition of people with poorly-controlled Type 2 diabetes.
Q. How does an MRI work?
Magnetic resonance imaging (MRI) uses a magnetic field and radio waves to create pictures of cross-sections. In many cases, MRI gives more information than other types of diagnostic imaging. Sometimes, contrast agents are used to enhance the images.

Q. Do we get sadder as we get older?
It seems that just the opposite is true. There’s a lot of evidence that we get happier the older we get.
A Gallup telephone poll of 340,000 in the United States concluded that happiness comes with age. However, the poll didn’t uncover the cause of this phenomenon.
Dr. Arthur A. Stone, a professor of psychology at the State University of New York at Stony Brook, was the lead author of a study based on the Gallup survey. He speculated on the causes for this happiness.
Q. What increases my chances of breaking a bone?
For several reasons, seniors are in danger of breaking a bone. As we age, the power of our senses, reflexes and coordination diminishes. Maladies and the medicines we take for them can contribute to balance problems, which can lead to falls. Then there’s osteoporosis, a disease that makes bones more likely to snap.
