Staphylococcus or staph is a group of bacteria that can cause a multitude of diseases. Staph infections can cause illness directly by infection or indirectly by the toxins they produce. Symptoms and signs of a staph infection include redness, swelling, pain, and drainage of pus. Minor skin infections are treated with an antibiotic ointment, while more serious infections are treated with intravenous antibiotics.
The good news is that muscle mass can increase at any age in response to exercise. In an important study of weight lifting and older adults conducted with 100 male and female residents of a nursing home in Boston (age range: 72 to 98 years of age; average age 87), subjects lifted weights with their legs three times a week for 10 weeks. At the end of the study, there was an increase in thigh mass of 2.7%, walking speed increased 12%, and leg strength increased a whopping 113%! In a similar study of adults 65-79 years old, subjects who lifted weights three times a week for three months increased their walking endurance by 38% (from 25 minutes to 34 minutes) without appreciable increases in mass. Ida Weiss, a 91-year-old participant in the Boston study, had the following to say after the study, "It's very beneficial for me. Things that I couldn't do when I came here, I can do now. I didn't think that I was going to live anymore, but I feel different now."

Adding resistance with light weights or elastic bands helps develop muscle mass and upper body strength. Sit (or stand) with feet flat on the floor and hold weights at shoulder height with palms facing forward, then lift the weights above your head. Other beneficial exercises for upper body strength include side arm raises — hold weights at your sides, palms inward, and raise your arms out to the sides — and front arm raises — hold weights at your sides, palms down, and raise arms to shoulder height. Aim for two sets of at least 10 reps for each of these three exercises.
Since accidental falls are a significant source of injury for many older adults, incorporating balance exercises in your exercise regimen is essential. Doing balance exercises, such as the ones described here, or an activity such as tai chi or yoga, makes it easier to walk on uneven surfaces without losing balance. You can do these balance exercises every day, several times a day — even when you’re standing in line at the bank or the grocery store.
One of the most exciting areas of exercise research is the investigation of cognitive function. What scientists have learned so far is that brain neurons, the special cells that help you think, move, perform all the bodily functions that keep you alive, and even help your memory, all increase in number after just a few days or weeks of regular activity. In a study in which researchers used an MRI machine to measure the amount of brain tissue in adults 55 years of age and older, they found results, consistent with other studies of aging and brain volume, showing there were substantial declines in brain tissue density as a function of age in areas of the brain responsible for thinking and memory, but importantly, the losses in these areas were substantially reduced as a function of cardiovascular fitness. In other words, the fittest individuals had the most brain tissue.
As you grow older, an active life is more important than ever. Even as the world tells you it's time to retire, relax, and take it easy, your body is craving for you to keep moving. And though you may be ready to retire from your 9-to-5, don’t hang up your walking shoes quite yet. The truth is that if you really want to enjoy these golden years and get more quality time from them, your best strategy is to exercise regularly.
In two different studies—one of men 50-70 years of age who lifted weights three times a week for 16 weeks, and the other of women 40-70 years of age who lifted twice a week for one year, bone density in the leg and back was shown to increase. There is also some evidence that walking can increase bone density in the hips and lower back, but the recommendation for frequency and intensity of the walking is not clear. What is clear is that exercise does help build or preserve bone density, and so it is recommended that we stay active for the sake of our bones and overall health.
Not only do leg raises help strengthen the thigh, hip, buttocks, and lower back muscles, this type of exercise benefits balance as well. For side leg raises, stand behind a chair and hold on for better balance. Lift one leg out to the side, keeping it completely aligned from heel to hip, while maintaining a straight back and a slight bend in the supporting leg, then slowly lower the leg. For back leg raises, use the same chair for balance and slowly lift one leg behind you (without leaning forward), hold for a moment, and lower the leg. Do not bend the lifted leg or point the toes, and keep the standing leg slightly bent. For each exercise, complete two sets of at least 10 reps for each leg, alternating legs between sets.
Carlucci’s older students were having some movement issues; their old ways of doing things no longer worked. They needed to learn new sequences for everyday challenges like getting up off of the ground after playing with their grandkids or picking up something that had fallen on the floor and putting it on a high shelf. Some had trouble with arthritis in their shoulders or knees.
