When shopping for shoes, you want to have more than fashion in mind — you'll also want to consider function and keeping your feet in good shape. These 10 tips can help you choose the right shoes:

1. Take a tracing of your foot with you. Place any shoe you think you might buy on top of the tracing. If the shoe is narrower or shorter than the tracing, don't even try it on.
2. Shop for shoes during the afternoon — your foot naturally expands with use during the day.
3. Wear the same type of socks to the store that you intend to wear with the shoes.
4. Have a salesperson measure both of your feet — and get measured every time you buy new shoes. Feet change with age, often growing larger and wider. If one foot is larger than the other, buy a size that fits the larger foot.
5. Stand in the shoes. Press gently on the top of the shoe to make sure you have about a half-inch of space between your longest toe and the end of the shoe. This provides enough room for your foot to press forward as you walk. Wiggle your toes to make sure there's enough room.
6. Walk around in the shoes to determine how they feel. Is there enough room at the balls of the feet? Do the heels fit snugly, or do they pinch or slip off? Don't rationalize that the shoes just need to be "broken in." Find shoes that fit from the start.
7. Trust your own comfort level rather than a shoe's size or description. Sizes vary between manufacturers. And no matter how comfortable an advertisement claims those shoes are, you're the real judge.
8. Pay attention to width as well as length. If the ball of your foot feels compressed in a particular shoe, ask if it comes in a wider size. Buying shoes that are a half-size bigger — but not any wider — won't necessarily solve the problem.
9. Feel the inside of the shoes to see if they have any tags, seams, or other material that might irritate your foot.
10.  Examine the soles. Are they sturdy enough to provide protection from sharp objects? Do they provide any cushioning? Take note of how they feel as you walk around the shoe store. Try to walk on hard surfaces as well as carpet to see how the shoe feels on both.

Being a caregiver for an ailing parent, spouse, child, or other loved one can feel like a lonely undertaking. It needn't, even if you don't have family nearby to pitch in. Help for caregivers is available from various organizations. Once you learn what's available, it may be easier to chart a less-demanding course toward meeting the needs of your spouse, relative, or friend.

Here are some types of services and professionals you might want to investigate.

Regular physical activity helps keep your heart, lungs, and muscles in shape and can stave off the effects of aging. In much the same way, exercising your brain can help keep your mind sharp and your memory intact. Here are two ways to activate your brain.

Keep busy and engaged

The MacArthur Foundation Study on Successful Aging, a long-term study of aging in America, found that education level was the strongest predictor of mental capacity as people aged. The more education, the more likely an individual was to maintain his or her memory and thinking skills. Other research has shown that people who held jobs that involved complex work, such as speaking to, instructing, or negotiating with others, had a lower risk of memory loss (dementia) than people whose jobs were less intellectually demanding.

Q. Whatever happened to the idea that taking vitamin C could boost your immune system and prevent colds? Is there still a possibility it could work?

A. Vitamin C, also known as ascorbic acid, was promoted as a health supplement for decades, achieving its greatest renown in the 1970s through the writings of scientist Linus Pauling. Despite the excitement about its natural antioxidant function, vitamin C does not appear to prevent colds, and its ability to shorten the duration of colds is minimal. A recent summary of 29 studies involving more than 10,000 people confirmed the lack of benefit of regular vitamin C supplementation.

If you feel run-down, lack of iron is probably not the cause. You can easily get enough of this key mineral in your diet.

Decades ago, advertising for the liquid vitamin and mineral supplement Geritol warned against "iron-poor, tired blood." It's a reference to the fact that red blood cells need iron to make hemoglobin, the molecule that grabs oxygen and transports it around the body.

This ancient practice may support heart health, general fitness, and mental well-being.

The new recommendations for healthy eating emphasize diet over individual nutrients and overturn some long-held beliefs.
