Q. I'm 68 and thinking of taking testosterone. Will it help me to feel younger?

There is some controversy about whether testosterone therapy should be used in men who have naturally lower testosterone levels because of aging. It remains unclear whether restoring earlier testosterone levels benefits older men.

For example, studies found that healthy men who took testosterone medications got bigger muscles, but in most studies the men weren't stronger. And, if you suffer from erectile dysfunction, taking testosterone may not relieve your condition.

The potential benefits of this therapy are: more muscle and strength, increased bone mineral density, thicker body hair and skin, elevated sexual desire, more energy, less irritability and depression, and improved mental capacity. Q. I have a problem with twitching eyes. Is that a symptom of anything?

Eye-twitching, also called eye spasms or blinking disorder, is known technically as blepharospasm. It usually is not a serious condition. Eye-twitching develops spontaneously. Smptoms of dry eye frequently precede it. In most cases, the eyelid spasms stop on their own.

The most common causes are fatigue, stress, prolonged staring, eye strain and caffeine. The best remedies are more sleep, relaxation techniques, reduced caffeine, warm soaks, eye drops, and correcting vision deficiencies.

You should see an eye doctor if twitching continues for more than a week, completely closes your eyelid or affects other parts of your face.

Q. How do you get Legionnaires' disease?

Most people become infected with Legionnaires' disease when they inhale microscopic water droplets containing legionella bacteria.

The legionella bacteria usually are found in water; they grow best when the water is warm. Legionella is often found in hot tubs, plumbing, water tanks, whirlpool spas on cruise ships and large air-conditioning systems.

If you choke or cough while drinking, you can get water in your lungs. If the water contains legionella, you may develop Legionnaires' disease, which is a form of pneumonia.

Those who are especially vulnerable to Legionnaires' disease are older adults, smokers, heavy drinkers and people with weakened immune systems.

If not treated, Legionnaires' disease can be fatal. Immediate treatment with antibiotics can usually cure Legionnaires' disease.
