But the other 364 days a year, we are in Washington, D.C. advocating for creator rights. We are in schools helping to educate young people. We also have a Health and Human Services operation called MusicCares, which is not just about addiction support, but but really for people in any kind of crisis, economic crisis or otherwise”“There's something about music and the way that music makes us feel that whether it is a classical artist, a jazz artist, a country artist, a hip hop artist, any EDM artist or rock artist, we're all in this music tribe, and it just really generates an incredible feeling of belonging.”“We want to make sure we're talking about craft, right? There are plenty of award shows that are about the most streamed artists, or maybe the artists that sold the most tickets or had the most revenue off of their tours or whatever. That's not us. We're a different thing.”Connect with JohnInstagramLinkedInThe Recording AcademyTranscriptSay hi to the AGEIST team!

There's something whether it's an activity or a hobby or whatever it is, there's something out there to go to, even no matter how big or small.I realize now when I have a problem or I'm worried or fretting about something, there are those people that I can text or pick up the phone and talk to that make me feel like it's all going to be okay. And that's what that community is about. That's what that small community is about.I watch my dad, who is 84. He goes to his gym, he meets people and goes out to restaurants by himself. He is determined to make sure he keeps doing that, even though a lot of his friends have passed away. And so I was like, Oh, he can do that. I should be doing that, because I think it's really, really hard and I think that sense of community is really necessary and really special. And I think that's kind of what we're all here for in the end.Connect with TamsenWebsitePodcastInstagramFacebook YoutubeSay hi to the AGEIST team!

Key Moments“The Goldilocks concept is really the goal, but it is really complicated and highly individualized, meaning balance is quite subjective.”“We're on the verge of developing generative A.I. Now we're considering both the risks and benefits of sentience, and I think that the way our brain works, we are naturally drawn to the risk before we're drawn to the opportunity. And I think that works, you know, like that's kept us here and that's brought us forward in our technologies.”“If God had a complete understanding of every physiologic system and all of its implications and interactions, what would God recommend we have for supper? Generative A.I. holds that potential. It would only inform us. So I think that, you know, the future is amazingly bright.”Connect with Dr. Chris RennaLifeSpanContactBookSay hi to the AGEIST team!

AmeriCorps Seniors — Get involved in your community through AmeriCorps Seniors’ volunteer opportunities and change your life. Go to AmeriCorps.gov/YourMoment Key Moments“So the traditional health care and medical practice in our country, in the US and most of the world concerns really considering everyone to be baseline healthy until they get sick to a level where they're very sick and they cross some kind of a threshold for diagnosis of having an actual disease. So even though we call it health care, a lot of people kind of pejoratively describe it as sick care.”“In short-lived species you can extend lifespans manyfold. One single gene mutation in worms can extend their lifespans by 10X, for example. And even in mice, we have interventions now that can extend their lifespans by 30% or 40% sometimes. And many of these interventions work across multiple species. So we believe they’re likely to work for people as well."“I wanted them to realize how big [the longevity field] had gotten so that they wouldn't delay getting into it with more serious amounts of money. They didn't realize that they were two years behind given how fast it was growing.”Connect with Karl PflegerXAgingBiotech.infoLinkedInSay hi to the AGEIST team!

Key Moments“Aesthetics was a goal of mine, but more importantly, as I had gained weight, my health declined. And what did that look like? I became pre-diabetic. I started having joint pain in my knees specifically. Unfortunately, I have 50 stairs from the ground level to my front door. I had to go up and down the stairs every day.”“Before, I wasn't even very good about getting my blood work done regularly. Now I do it twice a year. That's a huge part of my health regimen. I take supplements based on what my blood work says. And I think you have to be intentional like this if you want to age strong and healthy and vibrant.”“They see me muscular and in a bikini. And at 53, they say ‘that's not what someone should be doing.’ I do feel there is some of this ageism in those comments. I really do feel that. I also think we're very focused on: ‘well, you were fine before. Why did you do that?' – I wasn't fine. Right. I was pre-diabetic. I woke up exhausted. I felt like crap most days, right? My quality of life was poor. So I think we need to get beyond what we see and realize that this was a health journey.”Connect with DeniseRebellion BodyContactInstagramSay hi to the AGEIST team!

Habits Over Fads: Embracing Long-Term Health and Fitness with David Stewart

The episode is a blend of practical advice and motivational insights aimed at fostering a healthier, more self-aware approach to personal growth and well-being.Thank you to our sponsors: LMNT – our favorite electrolytes for optimal hydration.

What I have seen, I've seen this multiple times. I have engaged in this myself and I can tell you it does not work.”“We're looking to establish habits, habits that we can keep for a long period of time. Extreme diets are not a habit. They're sort of a short term occasion, and just a recipe for failure. We want to slightly modify what we're doing so that we can achieve it, so we can pat ourselves on the back and say “great job, reevaluate in three months.”“So this is an achievable target and it's measurable, which is really key about this.”Say hi to the AGEIST team!

Like just because you've had a few wins and adventures in your past doesn't mean that you need to hang up your hat.”“The longer we're in an environment where we're by ourselves, that's where this stuff gets really, really dangerous because we simply lose track of what's possible. So we retreat to autopilot, which works on the condition that you're very intentional with it. If you're not intentional and you don't have a process of getting around really high-level thinkers on a consistent basis, then you need to be conscious that that autopilot is going to eventually work against you”“It's really important to think about what season of life you're in and what is the metric for you to determine whether or not you're making the right progress. And sometimes just simply being on the right journey is enough. It doesn't matter about some of these other things that may or may not have manifested, just simply being on the right path and being aware of what's around you and putting one foot in front of the other, knowing that the universe is working for you.”Connect with JamesWebsitePodcastBooksGet in TouchSay hi to the AGEIST team!

So that's about as good as I get when people are sitting in my office and I'm doing it. And it's about as good as you get using varenicline or bupropion or nicotine patches as an alternative.”“They learned to control their pain with self-hypnosis so that a new pain in their chest didn't automatically mean to them that their disease was progressing. It meant they needed to do something to control the pain. And they did. So they had half the pain. And in our original study that we published in The Lancet, we found that the women randomized to work groups actually live longer than the control patients by an average of a year and a half.”“We found actually that people with breast cancer who were inefficient sleepers, who had trouble getting to sleep or staying asleep, actually also had shorter survival. But the other way around is that good sleepers live longer. It was having a long period of good 7 hours of consistent sleep at night, predicted with fewer disruptions, predicted longer survival with breast cancer.”“After a deep inhale, a slow exhale is important. And part of why it is is, you know, we're used to saying, you know, if you're anxious or tense, take a deep breath. Well, actually, the inhale actually tends to increase sympathetic activity because it reduces venous return or blood to the heart. If you think about it, you're lowering pressure in the chest.”Connect with Dr. SpiegelReveri App: Support someone who supports you this holiday season.
