You do not lose muscle because you get old. You get old faster because you lose muscle. Strength training is one of the most powerful tools we have to preserve independence, metabolic health, and longevity.

Aging isn’t what makes you weak. Being weak is what makes you age. Two of the most powerful forms of exercise for healthy aging are strength training and high-intensity interval training (HIIT). Both help your body build healthier mitochondria—the tiny power plants inside your cells that create the energy your brain, heart, and muscles need to function. And you don’t need a gym or an hour-long workout to benefit. Think of movement as “exercise snacks” throughout the day: • Stand up from a chair 10 times • Do wall push-ups • March quickly in place for 30–60 seconds • Walk fast enough that you can talk, but not sing Your starting point doesn’t matter. What matters is going from nothing to something—and gradually challenging your body as you get stronger. Thank you for having me on, CBS Mornings.

Most heart attacks today are not simply a cholesterol problem. Aside from a smaller group with inherited lipid disorders, many are connected to metabolic syndrome, prediabetes, and poor metabolic health. Too much sugar and starch can drive up insulin, triglycerides, and ApoB long before symptoms appear. The good news is that much of heart disease is preventable. Start with whole foods and limit ultra-processed foods. Combine aerobic exercise with strength training. Take a 10-minute walk after meals to help keep blood sugar under control. Prioritize sleep, manage stress, avoid smoking, and monitor your blood pressure. And do not assume that looking healthy means you know your risk. Go beyond the standard cholesterol panel. Ask your healthcare provider about ApoB, Lp(a), hemoglobin A1c, and fasting insulin. Check your blood pressure at home, track your waist-to-height ratio, and follow these numbers over time. Heart disease, high blood pressure, abnormal cholesterol, and insulin resistance are not separate problems. They are part of one interconnected biological system.

BREAKING: SpaceXAI has added a new guide called “Grok Bot 101” It explains how to create a personal AI teammate in just 10 to 15 minutes, teach it real workflows, connect apps, and build teams of specialized bots that continue working in the cloud even after you close your laptop. Here is the full guide in simple terms: • What is Grok Bot Grok Bot is an AI agent with its own persistent computer in the cloud. It has a desktop, files, terminal, browser, and apps. It can browse the web, use software, write and run code, and complete tasks just like someone using a computer. You can access the same computer from your phone or desktop. When needed, Grok Bot can hand control back to you for a CAPTCHA, 2FA, or secure login. • Creating a bot Give the bot a name, title, and detailed instructions. You can explain the workflow through chat or record yourself completing the task. Once trained, the bot can repeat that workflow whenever needed. It can also use MCP servers, plugins, skills, and connected services such as Gmail, Google Calendar, Google Drive, and Slack. • Three ways to use Grok Bot Send it a message in chat. Create schedules or triggers, such as monitoring a Slack thread or GitHub PR. Allow bots to message and activate other bots. • Permissions and safety You can write rules in normal language explaining what the bot can and cannot do. A separate review agent checks proposed actions and can allow them, block them, or ask you for approval. Allow and block lists provide additional control, while the work runs inside an isolated environment. One important detail: if you log into a website with one bot, other bots using that shared cloud computer can also access it. • Multi-bot teams You can create specialist bots for different jobs and let them work together. One bot can ask another for help, several bots can work inside a group chat, and a scheduled routine can move a task through multiple specialists until the work is finished. • Personal CRM The author created a bot that turned the 800 to 900 people he follows on X into a private Notion CRM containing public profile information. It helps him find and reconnect with people when traveling. • Arnold, the fitness bot He replaced a complicated fitness app with a Grok Bot strength-training coach named Arnold. The bot uses MCP servers, plugins, and skills while requiring less maintenance. Its behavior can be updated simply by chatting with it. • Building software Grok Bot gathers information from Slack, Notion, GitHub, documentation, and other sources. It then creates a clean prompt and sends it to a specialized Cursor cloud agent that builds the software. Grok Bot handles the planning and coordination, while the coding agent handles the actual build. • Searching company knowledge Grok Bot can search across codebases, Slack conversations, Notion pages, GitHub, and internal documents to answer product or company questions. This helps people find information faster and reduces the need to interrupt coworkers. • The biggest takeaway Instead of repeatedly building scripts or complicated apps, you can describe a workflow to Grok Bot, improve it through chat, reuse it, and let it continue working in the cloud. Grok Bot is not just another chatbot. It is a real AI teammate with a computer that can use tools, coordinate specialists, and get actual work done. The future of work is becoming incredibly exciting.
