Dr. Oz took "Extra" correspondent AJ Calloway's blood pressure, which was 110 over 75. "That, my friend ,is perfect!" exclaimed the physician. That's the ideal blood pressure. And you know what? If it's 140 over 90, your life expectancy is 8 years shorter than if it's what it is now."

"Extra" Lifechanger and CBS News Travel Editor Peter Greenberg reveals how you can creatively travel and without taking out a second mortgage on your home.

Greenberg says a wise start to planning your travels is online. "Momondon.com searches for over 600 different websites to get you the best fare," he says.
Planning a trip at the right time of the year is also key. "If you can book a trip during September, you get the best weather and the best deals, and you get the best service," Greenberg advises.

You don't have to wait until October to become aware. Learn how you can become "Breast-Aware" now!

Breast health and awareness is important at all ages, not just after 40. Second to skin cancers, breast cancer is the most common type of cancer found in women. Every woman needs to know if they are at risk. In recognition of Women's Health Month, here are some easy ways to become more aware of your breasts:

Understand your risk level: Know your family's health history and talk to your doctor about your personal risk of breast cancer.

Screenings: Ask your doctor which screening tests are right for you if you are a higher risk. If you're 40 or older, have a mammogram every year. If you're 20 or older, have a clinical breast exam at least every three years.

Know what's normal for you: See your doctor right away if you notice any of the following breast changes:

--Lump, hard knot or thickening
--Swelling, warmth, redness or darkening
--Change in size or shape
--Dimpling of puckering of the skin
--Itchy, scaly sore or rash on the nipple
