[Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **“Digital Device Detox,”** a guide to breaking free from the addictive and destructive powers of social media and apps, with Jillian Tucker, licensed clinical social worker in private practice, adjunct professor of clinical social work at Columbia University and New York University, and therapist with nearly 15 years of experience in addiction treatment and behavioral change. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/northern-virginia-digital-detox](https://events.ticketleap.com/tickets/profsandpints/northern-virginia-digital-detox) .] Many of us have had the same experience: We’re trying to get things done and stay focused on the positive in our lives, but we can’t stop looking at a cell phone that tells us that we live in troubled times, that everyone else is better looking and having more fun, and that escape awaits in the worlds of Candy Crush or Pokémon Go. Maybe it’s time to find effective ways to loosen the grip of that cell phone and rediscover the happiness that comes with using digital devices less. Join Jillian Tucker, who previously has given several excellent Profs and Pints talks related to mental health, for a crash course on how to restore balance in your relationship with digital devices to ensure they’re simply tools you use rather than instruments through which other people use you. She’ll start by discussing social and mental-health trends connected to the use of digital devices. We’ll delve into the specific ways that their overuse can be biologically and psychologically harmful and leads to division, depression, anxiety and anguish on an individual and societal level. Professor Tucker also will look at why digital habits are hard to break, citing neuroscience and what we know about behavioral addiction. You’ll learn the many ways in which devices and apps are deliberately designed to be hard to stop using. You won’t be urged to just chuck your cell phone, though. After all, such devices can keep you socially connected, be sources of joy and learning, and even save your life if you need to summon help in an emergency. Instead, we’ll look at effective strategies for reducing digital device use, considering approaches that treat the overuse of such devices as “addiction” but moving beyond them to consider more nuanced ones as well. We’ll explore how to find our core motivation to change and how to carry out a change plan. We’ll consider how those who failed in past attempts to reduce digital-device use can overcome impasses in their effort to change their behavior. We’ll discuss ways to minimize the feelings of inconvenience and withdrawal that might come with reducing digital-device use, and we’ll discuss strategies for regaining the social skills and reviving the in-person strategies that our device use had compromised. You’ll learn how the same conditioning and power of habit that got us using our devices so much more also can be harnessed to help us use them much less. You’ll learn how to curate and enhance the positive aspects of digital devices, to help maintain them as a source of connection, joy, humor and learning and keep them from causing you unhappiness or stress.

​​**Let's discuss a ted talk video while taking a walk at Capital Crescent Trail Near Bethesda.** **To receive future event updates, register on Luma:** [https://luma.com/tv3fhasq](https://luma.com/tv3fhasq) Have you had your daily dose of fun? It's not just enjoyable, it's also essential for your health and happiness, says science journalist Catherine Price. She proposes a new definition of fun -- what she calls "true fun" -- and shares easy, evidence-backed ways to weave playfulness, flow and connection into your everyday life. ​​​​Here is how it works: * ​​​​​​​Prior to the event: **Please watch this YouTube video:** [https://www.youtube.com/watch?v=iMBJrvEwv8s](https://www.youtube.com/watch?v=iMBJrvEwv8s) * ​During the event: * ​​3:30pm-3:45pm: meet outside of [Chopt Salad](https://maps.app.goo.gl/ThxMNixG2TG4T32X6) (Bethesda Row end of Capital Crescent Trail) for group introduction. * ​3:45pm-4:45pm: Take a walk at Capital Crescent Trail (laps between Bethesda Row and Little Falls Parkway) and Discuss. * ​(Walking Route Link: [https://scenic-walk.com/#/b712c5fa ](https://scenic-walk.com/#/b712c5fa)(During the hike, the organizer will live broadcast current location, so that people who arrive late can catch up via the [Scenic Walk Link](https://scenic-walk.com/#/b712c5fa)). * ​4:45pm - 5pm: Group Conclusion outside of Chopt Salad. *** ​​​​Discussion Questions During Walk: \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- 1. **True fun is a visceral feeling of being illuminated from within rather than just a leisure activity. How can we better distinguish between activities that merely pass the time and those that truly make us feel radiant?** 2. **Playfulness involves a lighthearted attitude of doing things for their own sake without worrying about the outcome. How might our community change if we collectively lowered our guards and let go of the need for perfection?** 3. **Most peak fun memories involve a shared experience that helps us feel united with others. In a polarized world, how can the pursuit of fun serve as a bridge to connect us as human beings?** 4. **Fun requires a state of flow where we are so engaged that we lose track of time. What environments can we create together that naturally encourage us to be fully present and focused on the moment?** 5. **Prioritizing fun acts as a legitimate health intervention by reducing stress and promoting social bonding. How would we shift our schedules if we viewed joyful moments as essential to our physical and mental well-being?** 6. **Constant digital distractions interrupt our flow and prevent us from forming real-world connections. What boundaries can we set with our devices to ensure we remain available for spontaneous moments of joy?** \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- To provide an enjoyable experience for fellow participants, here are three ground rules during discussion events: 1. Step up and step back. (If you feel that you’ve been talking too much, step back to listen more. If you feel that you’ve been relatively quiet, step up to share your perspective or ask a question) 2. Listen to understand, not to respond. 3. Be open-minded and value differences.

So this month's prompt is more general. I think we can all agree that we are living in "unique" times that require coping skills. I think that one role and/or purpose of philosophy is to help us deal with our daily lives and our "unique" times. So, let's share our feelings and thoughts about which philosopher/philosophy we turn to in order to deal with our crazy events. Who/what helps you stay focused in your daily life and helps you sleep at night. I find that Stoicism with a little philosophical pessimism mixed in goes a long way in helping me deal with what I see as very destructive, fearful and mean spirited public policies at both the state and federal levels. Hope to see you on March 28th!

Private Group. Closed to the Public Knowing ourselves and understanding our abilities is the first step toward wielding our gifts with control and accuracy. In subsequent classes we will verify and hone our talents with activities and discussion. These are hands-on workshops and participation is expected. The goal of our series will be to develop expertise in areas of particular interest such as mediumship, channeling, divination, healing and, etc.. Our ultimate directions will be determined by class members as we evolve. I look forward to sharing and discovering with you. - Cynthia

The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 **Abstract** Web Forms gave .NET developers a powerful abstraction for building reusable UI controls long before design systems were a thing. Web Components finally bring that same idea to the browser natively. This session explores how the Web Forms mindset translates into Custom Elements, Shadow DOM, and HTML templates. We’ll examine how Web Components enable design systems that work across frameworks, how they differ from server‑driven controls, and why they’re becoming a foundational layer for modern UI. Whether you’re maintaining legacy apps or building greenfield projects, you’ll leave with a practical understanding of how to apply familiar patterns in a modern, standards‑based way. **YouTube Link** TBA
