Career Re-Boot, You Are Stronger Than You Think You Are: Wendy Perrotti
Many of us believe that what limits us are our external circumstances. However, we are often internally self-limited. When we push back on our limiting beliefs, we are capable of any and everything. Wendy Perrotti, co-founder of Camp Reinvention, and David Stewart, founder of AGEIST, discuss these self-limiting beliefs and the possibilities that follow when we stop believing in them, where the attitude of fragility comes from when society is looking at someone in midlife and beyond, the importance of feeling useful, why we must search for our purpose rather than our passion, and much more. What you will learn in this episode:- Why we hold self-limiting beliefs, how to let go of them, and the possibilities that follow- Why society views us as fragile- Why we must continue to feel useful and helpful to others- Why we need to look for our purpose, not our passion“The burden that most people feel is ‘What if?’ “I’ve never seen anyone who truly succeeds forward. Every success is almost like an ending point. We fail forward. It’s everything that you try and fail and try and twerk and play with and experiment with that actually moves you forward to those successes that are like bam! Did that, check it off the list, and then we fail forward again.” “All of those little things that you have lived through, that you have triumphed over, that you have merely survived, if you notice them for the win of it rather than for the pain of it, my god, by the time you hit our age, we feel completely invincible!” Listen to the SuperAge podcast wherever you stream your pods.

Unlocking the Secret to Better Energy: Dr. Michael Breus, The Sleep Doctor
Want to improve your health and boost energy? Align your life with your chronotype and body type to better understand when to fast, exercise, and sleep. If we aren’t getting adequate sleep, a lot of physical and mental problems can follow from the obvious symptoms like fatigue and brain fog to more serious things like increased risk of dementia. What is an adequate amount of deep and REM sleep? What are the minimum and maximum amount of sleep we need each night? What should we do if we wake up in the middle of the night? What’s the deal with intermittent fasting and sleep? Should we take melatonin? We have had Dr. Michael Breus, The Sleep Doctor, on the SuperAge podcast twice and now he returns for a third time to answer these questions and more. What you will learn in this episode:- How our body types and sleep chronotypes can inform what sleep schedule we would thrive on- Why it is so important to have a consistent sleep and wake routine- The minimum amount of hours we need to sleep each night to function properly- How much sleep is too much sleep- What to do if you wake up in the middle of the night- Melatonin’s role in sleep- The importance of vitamin D“When you wake up in the morning at a consistent time, let’s say it’s 6:15, when the sunlight hits your eyeball, you have special cells in your eyeball called melanopsin cells. These turn off the melatonin faucet in your brain which allows you to kind of clear the brain fog and wake up. The more consistent you are with it, the more your body can expect when to turn off the melatonin faucet. When it turns off the faucet in your head, it sets a timer for roughly 15 hours later to start melatonin.” “You would actually be considered drunk behind the wheel if you get less than 5 1/2 hours just from a reaction time standpoint.”“Sleep is a lot like love: the less you look for it, the more it shows up.” “If there are folks out there who do like to get up around daybreak, there’s actually data to suggest that watching the sunrise, is very healthy for your circadian rhythms and very good for your eyeballs.” Thank you to our sponsor InsideTracker.

Gut Health, Microbiome, and the Brain. Everything You Need to Know: Dr. Emeran Mayer
“Gut-health” has become a buzzword in the wellness industry, but what exactly is our gut and how do we know if it’s healthy? What role does it play in our overall health? What is its connection to the brain? Do probiotics or fermented foods do any good for our gut? Does fasting impact the gut microbiome? What are 5 things we can do for a healthier gut? Dr. Emeran Mayer, gastroenterologist, author, neuroscientist, and professor in the Departments of Medicine, Physiology and Psychiatry. At the David Geffen School of Medicine at UCLA joins us on the SuperAge podcast to discuss these questions and shares his expertise on the gut microbiome. What you will learn: What the “gut” and “microbiome” actually areHow the health of our gut impacts the health of everything else in our bodiesThe guts connection to our brainWhether probiotics and fermented foods really work for improving gut healthHow fasting may impact the gut5 things to do for a healthier gut“I think what we have observed is that our modern lifestyle is not very conducive to a healthy gut because of what we eat and the whole standard American diet story that plays a significant role.” “What happens in the gut does not stay in the gut. It goes through various signaling molecules to every part of the body.”“If you’re stressed in your brain, or you have negative emotions in your brain, your gut knows it, because it gets these signals. And vice versa, if your gut is imbalanced, your brain knows it.” Thank you to our sponsor InsideTracker.

HRT, Estrogen and Menopause, New Scientific Findings: Dr. Rebecca Dunsmoor-Su
Much of what is thought about hormone replacement therapy is outdated and untrue. We do a deep dive into what is HRT, what are the benefits, and who should and should not be taking it. What happens during a women’s hormone journey from childhood to post-menopausal? How are hormones and a woman’s brain connected? What happens in a women’s body during menopause? What is hormone replacement therapy? Does HRT increase the risk of breast cancer? What is the relation between hormones and the cardiovascular system? How does menopause impact sleep? Dr. Rebecca Dunsmoor-Su is the Medical Director of Menopause services at the Women’s Wellness and Gyn Specialties Clinic at Swedish Medical Center. She is also the Chief Medical Officer at Gennev. Dr. Dunsmoor-Su joins us on the SuperAge podcast for an information-dense episode all about menopause. She explains what happens leading up to and during menopause, some of the symptoms like weight gain, trouble sleeping, brain fog, and how they are addressed, how we can use hormone replacement therapy to improve symptoms and longevity for women post-menopause, and much more. What you will learn in this episode:What a woman’s body goes through in terms of hormones from childhood all the way through post-menopause The impact of menopause on the brainEverything we need to know about hormone replacement therapy and some of the myths around itHow menopause impacts sleep and what can help How menopause impacts brain health and the cardiovascular system “Estrogen replacement does not cause breast cancer. And I like to shout that from the rooftops. We have many studies that tell us that estrogen replacement does not cause breast cancer.” “Women who start hormone replacement therapy within 5 years of their last period actually reduce their cardiovascular risk. They also slightly reduce their risk of colon cancer and they reduce their all cause mortality overtime.” “When women are transitioning through menopause, we’re talking about 5-10 years of disrupted sleep. That’s a lot of impact to the brain.” “Menopause is fine and functional if you’re going to live to be 65. You’ve got 10 years to survive menopause, you’re going to be okay. We live to 95, 100, 105! That’s a long time, that’s almost half your life without the hormones that sort of keep things going. So I think that we need to adjust.” Listen to the SuperAge podcast wherever you get your pods.

The Real Truth About Keto, Fasting and Longevity: Jim Howard
What is the importance of biofeedback for longevity and improved physical performance? How can we accurately measure whether we are in ketosis? What is intermittent fasting? What impact does an 18:6 diet really have on our bodies? What is autophagy? How does fasting affect muscle mass? What are exogenous ketones? What does it mean to be metabolically flexible? With all of the conflicting information surrounding ketosis, fasting, the impact of exogenous ketones, and nutrition as a whole, we wanted to get an expert on the SuperAge podcast to give us some clarity around the topic. Jim Howard, the President and CEO of Readout Health, has helped to create an innovative biofeedback tool, Biosense, used to measure your ketone levels throughout the day to help with goals for longevity, weight management, or peak performance. He, along with this team at Readout Health, wants to help us regain control of our health through proper nutrition and lower the rates of obesity, type 2 diabetes, heart disease, and more. What you will learn in this episode:- Why using a biofeedback device can promote a better understanding of our health and be used to promote longevity- How to know whether you’re in ketosis- The misconceptions around ketosis, health, and diet- What intermittent fasting does for the body- What autophagy is and how it impacts aging- What Jim’s wellness non-negotiable are“A good way to look at ketosis, I don’t mean the keto diet I’m talking about ketosis, is that it’s the other side of the metabolic switch, that’s where the damage is undone. We focus on the undoing of the damage that one has done to themselves.” “If longevity and healthspan are curious and part of your future plans, I encourage it to be, knowing what your actual body is doing as you enter these zones is critical, as opposed to just guessing.” “I was born in 1967 and in this one generation, in 1967 10% of us were obese. 54 years later it’s now at 40%. In one decade it will be 49%.”Try Readout Health’s Biosense ketone monitor with code SUPERAGE20 on https://mybiosense.com. Listen to the SuperAge podcast wherever you get your pods.

She wants to talk about menopause and aging in a way that is productive and meaningful.How are women unprepared for menopause?
