America's doctor, Mehmet Oz, wants you to help you get on the path to living better.

"It's pretty simple: You've got to show up in your own life. Too many of us think showing up means literally walking out when it makes sense. We back our way through life, we don't bring together the team. There's never been a championship won by someone that didn't show up on the field.

So, you've got to pull it all together, bring the people around you that you love dearly, the folks you think can help you, the mentors you need, and pay attention to what we're talking about today because these are life lessons that can drastically change your life and the people around you as well. And we're going to do it all together." Let the advice-a-thon begin!

Dr. Oz tackles your health questions:

1. I'm too tired to think about sex. How do I get my energy back?

2. How can I live longer? And what does your "real age" mean?

3. What is my blood pressure and why is it important?

4. I hate vegetables! Why do I have to eat them?

5. What are the red flags that show I am aging too fast?

6. What is a vulva?

7. Why is splurging so bad and what can I do to counteract it if i do?

8. Why do I have a third nipple?

9. How can I live my best life this year?

Go to the first question

I used to be a real sex kitten with my husband. But now I'm too tired to even think about sex. How do I get my energy back?—Molly from Los Angeles

Dr. Oz: Try wake-up sex. That's why guys get erections in the morning—it's the best time hormonally for us. The women usually are enticeable at that hour because you haven't done anything wrong yet. So, you can make magic happen.

So what's ideal? The sexual famine that we're experiencing in this country reflects lots of things that are happening in our lives; I'm going to turn to Dr. Phil for that in a second. But let's go through what's happening in your body. If you can't rev your engine, if you can't figure out if all the parts are working, it means that there's a big issue that you've got to deal with in your body.

So, if you're having sex once a week, which is the average in America, it's actually 56 times a year—just about once a week. If you go to twice a week—just doubling it—you will live three years longer. Are you all hearing that? Now the guys out there, you've got an excuse!

The real question I want everybody to think about is: "Why is it so darn important?" Well, let me give you a couple of numbers. Is it the physical activity? Well, the actual intercourse in America burns 23 calories: It's not that. It takes about three minutes: It's not that.

Now what it does do is it brings you the connection with someone that you care for. When you're doing it with someone that you care for, it adds up and builds a bond that you have, which allows you to thrive in life. It also does in fact check to make sure that the major blood vessels of the body are working, because you know what? If nitric oxide, which is this short-lived gas that a Nobel prize was awarded for that allows the penis to engorge—if that's not there, then it's not there in your heart or your brain or your kidneys or anywhere else. The foods you eat and the activities you do influence exactly how well the erection functions. And if you're having that, it ain't going to work.

I think ideally America would have sex at least twice a week. I think three times [would be] even better. And let me give you a quick checklist that I think will help. Number one, you've got to take the television out of the bedroom, because if the TV's in the bedroom, it's going to distract you. Number two, sleep naked. It's self-evident: Take away the barriers. And women, please, the guys love your bodies. You guys are complaining about them, I don't care if it's cellulite or if your breasts are sagging—the guys like it and that's why they married you. It wasn't an accident.

I think probably the most important advice I'll give: don't start off saying, "Hey, let's go have sex," because that's intimidating. The first thing you want to do is cuddle. Just touch people, get close to them. You want to be able to touch and cuddle on folks, and the most sexual organ in the body is the brain. For guys, please, it's a 24-hour process for women. Call them, text them, talk to them—that's the first thing you ought to do, combined with the cuddling to make magic happen. If you do all those things, you bring up the one final issue: I've always told folks on my show that if you don't feel like it, you should still push yourself to do it. Even if you don't feel like having sex that day, if the person you love wants to have sex, you ought to push yourself to do it.

Next: How can I live longer? And what does your "real age" mean?

Over the last few weeks, thousands of emails have come in asking Dr. Oz this question: "How can I live longer?" Now I remember when you did this for me when I was 50, and my real age was 38, and I was so excited about that. I'd be scared to take it today. But what does it mean, "real age"?—Gayle King, Host of Oprah's All Stars

So, a lot of folks when they want to figure out how old they are, they'll do the math. They'll figure out what day was I born, what's the day, subtract it from, and that's what they think their age is. That's wrong.

You want to know how old your body thinks you are. That's your real age. You know, when you go to your high school reunion, not everyone looks the same even though most of you are the same chronological age, but the physiologic age—how old your body thinks you are—is different.

So, real age is an effort for us to measure that number. And the reason it's so important is because it makes you an adult. It tells you what's causing you to gain age, lose years of life and, for that reason, what you might want to focus on to improve on that. And the biggest news I'm going to talk about today is the fact that if you change your lifestyle over the course of three months, quarter of a year, you can reverse most of the mistakes that you have made, and they're affecting your aging.

That's a dramatic insight that we only recently learned about. But give me three months, and we'll put you back where you could have been your whole life.

Next: What's so important about blood pressure?

Now Suze, you're a numbers person. What's your blood pressure?—Dr. Mehmet Oz

Suze Orman: I don't have a clue

Dr. Oz: Listen, there are some things in life you just need to need the numbers on. There are some mysteries out there we're never going to figure out, but this is not one of them. This is something that is knowable and fixable.

The 9 numbers every woman should know

Blood pressure is the number one cause of aging. And you know why? High blood pressure scrapes off the delicate lining of your arteries, which the body's got to fix with whatever it has. And the plaster of the body that fixes the holes punched in your arteries by the high blood pressure is cholesterol.

So if you've got high blood pressure and high cholesterol, of 296, I can guarantee you're making a lot of plaque in there. And that plaque is the kind of stuff that causes the strokes, heart attacks, impotence—all the things we talk about day in and day out, and it is reversible.

Next: Why Suze Orman should eat her vegetables!

Dr. Oz, I hate vegetables! I'm not a big vegetable person. I don't know why, never have been. I'm like one of those kids who don't like spinach, "Oh please, no momma!" All right, so I'm not going to eat vegetables, Doc.—Suze Orman

Dr. Oz: You know, the thing about vegetables is that vegetables are the way you cleanse your liver. They're the way you filter through the junk in your body.

Double Delicious cooking tips for a balanced diet from Jessica Seinfeld

They're the nutrients that you get from the sun via the plants that give you the ability to live your best life. So, we've got to add vegetables on your list.

Next: What are the red flags that show I am aging faster than I should?

Dr. Oz: I'm going to give you three tips you can do today, practically as you watch the show. The first is: the ratio of your index finger to your ring finger. Most of the time, men will have a longer ring finger than index finger. Women generally won't. They're about even or actually the opposite with the index finger being longer. If you have a longer ring finger, you have a higher incidence of osteoarthritis. In fact, it's twice the incidence of osteoarthritis.

Dr. Oz and the arthritis cure

However, if you've got a ring finger that's longer, you have higher testosterone levels and it gets longer because you saw testosterone in your mother's womb, so you'll often have higher sperm counts. So, it's good and a little bit of bad, but it's something you can learn about your body.

The second big thing is your bra size. If your bra size at age 20 is a size D, then guess what? You've got a 1-1/2 times higher rate of developing diabetes—a fifty percent increase of chance of diabetes.

Why diabetes is America's silent killer

And the third tip I'll throw out there is your earlobe. If there's a vertical crease in the earlobe coming down, that vertical crease is because the blood flow to that lobe isn't where it needs to be. And because of that it'll crack. That little vertical crack (that line in your earlobe) is an indicator that you are at more risk for heart disease.

8 ways to save your own heart

So those are three tips, easy physical exam traits, that we as physicians use.

Next: What is a vulva?

What is a vulva?—Ross Matthews

Dr. Oz: All right, vulva. If you're getting into a shower and if you're a female, and you take a mirror and look at your private parts—that's the vulva. So it's the labia majora, the labia minora, that runs into the clitoris on top. And then, down below there is the vestibule, or entryway, into the vagina. That whole area is called the vulva.

And it's important for us to understand that because if you don't understand your own anatomy, you're not going to be able to understand how to make the most out of it.

Next:Is it ok to splurge at the buffet sometimes?

We think that everybody loves a good buffet. Unfortunately, most people have trouble controlling the urge to—well, basically to eat everything. Even I have a problem with buffets—I end up eating things I don't want to just because it's there. And so I'm eating waffles and the salad and the bread and the croissants and the desserts—it doesn't make any sense. —Gayle King, host of Oprah's All Stars 

Dr. Oz: Buffets make it hard to do the right thing. And unfortunately, as much as I love to splurge, it's not, you know, rocket science.

What I love the most about the whole experience, is that you recognize that if you’re given the option to choose all the things that might drive you in the wrong direction, you’ll make all those wrong choices. There's no GPS that's going to point out the right ones.

Strategies to avoid stress eating at the holidays and beyond

The food you ought to eat should look the same when it comes out of the ground as when you put it in your mouth. That's what real wholesome food is about. I understand [those foods] and you will too if you think about it. And they're not involved in that buffet unless you look carefully.

The other thing is, you can never ever exercise away the food you eat by itself. It cannot be done. You'd have to exercise for 24 hours to burn off those calories. It is impossible. What you've got to do is both: Be smart and thoughtful about your exercise, and combine that with smart decisions about how you eat—and that is the marriage that makes you live a long time.

Gayle King: So, Dr. Oz, are you telling me that when I splurge—Christmas, Thanksgiving...— then if you say, "I'll just do an extra workout" or "I'll work out longer or harder," that really doesn't do any good?

Dr. Oz: It does do a lot of good. As soon as you work out, if you can work out within a couple minutes of eating—just a little bit, some simple exercises—you open up the muscles to the sugar. So the muscles, which are a metabolic furnace, take the sugar into them and they burn them off. But you'll only burn off a couple hundred calories.

Next: Why do I have a third nipple?

I've got a third nipple, and I was just wondering why.—Nick

A third nipple is very common actually, Nick. About five percent of humans have a third nipple. Most mammals have mammary lines coming down, right? Multiple things you can suckle off of. If you're a pop, you've given birth to multiple children. So in humans we lost that. We only need to have two because we rarely have more than two babies at once. But sometimes you get remnants. And I've seen quite a few of these.

This is an example of the differences that we have among us, and those differences make us who we are. And most folks who have extra fingers or weird things growing on parts of their body, they're just a remnant from our embryology, from our genetics.

You're born with the extra nipple, and it usually reflects that there was something that went on when you were in your mother's womb that stimulated something in one direction versus the other direction. The only thing that I might worry about is that sometimes people with third nipples have heart problems.

Next:How can I live my best life this year?

How can we live our best life this year, Dr. Oz?—Gayle King, host ofAsk Oprah's All Stars

Dr. Oz: I had a dear friend who passed away recently and we were looking back at something that he had written when he was in high school. And he said he'd wished that his children would have at least one moment of real pain, of real discomfort.

That's sort of a strange thing to wish on the people in your life that you love the most. But he's a very thoughtful man, and we learned that what he was really talking about was the fact that pain is the foil of joy, of love, of life. And I think as a nation we've gotten really uncomfortable being in pain.

So what I'm asking you to do is to be comfortable being uncomfortable. I want you to deny yourself an indulgence. In part, to see what it feels like, and then write it down. And experience what it's like because that's what makes us who we are. Create a little discomfort in your life because that's how we grow. Not all stress is bad. And how you cope with it is really what matters.
