Men's Group meetup
Men's Group meetup
**The idea for this group is to build a community where men can gather together and build connections & learn and grow from each other.** How we start each meeting is by each of us checking in with our "roses and thorns" aka what are the good things and the bad things going on in your life recently? Then we will go into a topic discussion. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **COMMUNITY AGREEMENTS** \*\*THERE WILL BE A ZERO TOLERANCE POLICY FOR NO-SHOWS. IF YOU RSVP TO A MEETING AND FAIL TO SHOW UP WITHOUT NOTICE, YOU'LL BE REMOVED FROM THE GROUP. THIS IS TO PRESERVE THE INTEGRITY OF THE GROUP\*\* 1. Confidentiality - EVERYTHING that is shared NEVER leaves this space so that this space remains safe and sacred. There is a zero tolerance policy for this. If a man is in violation of this, they will be permanently removed from the group. 2. Non-Judgement - we respect and honor every man’s truth so that we may receive the same from others. While we may not agree on everything, we commit to respecting every man’s perspectives and engaging in honorable discussion with one another. 3. Be committed - honor your commitment to this group and to yourself. If you attend a meeting, please commit yourself fully to the meeting. Also be committed to your own journey. When we fail, we own it & clean it up. 4. Speak from the heart - this is NOT a space to “look good”, have the “right” answers, and have it all together. Relax and know you are not alone. Be exactly who you are within the safety of this space. 5. Be supportive - This means always willing to provide encouragement to your fellow men, encourage action and momentum in each other’s lives.. Be willing to challenge each other. Be willing to hold each other accountable. 6. Participation - what you receive from this community will be a reflection of what you put into it. Period. We ask that you share your perspectives, reflect on others, and give/receive support when and where it’s needed.

Drunken Philosophy: Are you really who you think you are? What is the "self"?
Drunken Philosophy: Are you really who you think you are? What is the "self"?
I have been studying the question of "self" online with Prof. Ellie Anderson and so I thought a prompt on the "self" might be interesting. Full confession: I had Claude create this prompt and I like it, so here goes: Imagine a thought experiment that merges two classic puzzles: > You undergo a procedure, performed neuron by neuron, in which every biological component of your brain is replaced with a functionally identical synthetic substitute. At each step, your behavior, memories, and personality remain unchanged. When the last neuron is swapped, is the consciousness experiencing the world still you? And — more pressingly — was there ever a continuous "you" to begin with? ### Questions to Wrestle With * If consciousness is purely physical, does the *gradual* nature of the replacement matter, or is it equivalent to being destroyed and rebuilt? * Could there be a "self" without continuity of experience — even moment to moment, while you sleep? On a more practical level, consider the simpler case first: **hemispherectomy** patients — people who have had an entire cerebral hemisphere surgically removed — often retain a strong sense of personal identity and continuity. This suggests "you" are not rigidly tied to specific physical material. But does that vindicate the synthetic neuron case, or merely show that identity is more *flexible* than we thought — not that it can survive *complete* substrate replacement? I used Claude so I could get this out today and let everyone have some time to consider it. Hope to see you at the Oracle. Sorry about the location change two weeks ago. That's what I get for trusting local weather predictions!

Walk & Talk About Life's Big Questions
Walk & Talk About Life's Big Questions
[The Board Walks](http://www.theboardwalks.com/) are for curious people who love deep conversations. If that sounds like you, **bring a thoughtful topic** and join us for a 5-mile walk (10,000+ steps!). **HOW IT WORKS** **Step 1: Bring a topic** Before you arrive, think of **one** topic you want to explore. A question. A thought that's been on your mind. An obsession you want to geek out on. This is your ticket to the event. **Step 2: Circle up & share** We gather in a circle. Your friendly walk host gives a speech to set the tone. Everyone shares: your name, what you're grateful for, and your topic. That's it. 60 seconds. **Step 3: Walk, talk & float** We walk 5 miles. You naturally drift into conversation with 2-3 people at a time, pulled by topics that spark your curiosity. When you're ready to move on, just say: "I'm going to float!" **Step 4: Feel more alive** Two hours flies by. You're back where you started — but you feel different. More alive. More energized. More connected to yourself and others. That's why regulars join 20+ times. *For more details, read our [Orientation Guide.](https://www.theboardwalks.com/orientation)* **HOW TO BRING A GREAT TOPIC** A great topic = something you're genuinely curious about. Recent topics include: * "What are you passionate about right now?" * "What makes a good friend?" * "What's a belief you used to hold that you've completely changed?" * "How do you want to be remembered?" * "What would you do if money wasn't a factor?" Think of your topic like the dish you're bringing to our conversational potluck. If everyone brings an A+ dish (i.e. energizing, uplifting, expansive), we'll all walk away feeling lighter and brighter. **WHAT TO EXPECT** This isn't a fitness event with casual chitchat. It's a walking think tank where we explore life's big questions together, beyond small talk. *If you're looking for light banter or a standard networking event, this probably isn't the right fit.* But if you crave depth, genuine connection, and conversations that make you feel alive? You'll love it here. **FAQ** * Wear casual athletic attire and sneakers. It's a long walk! * We have multiple first-timers at each event. We work hard to create a welcoming, inclusive, clique-free space. * We welcome people of **all** ages, backgrounds, and industries who align with the [intention](https://www.theboardwalks.com/ground-rules) of this space. * Rain or shine, we've been out here nearly every week since July 2022. If the event is cancelled, we'll let you know. * Dogs, babies in strollers, parents, and friends are welcome — please text/email them the event link so they can RSVP and prepare a topic! **LOGISTICS** * If you'll arrive over 10 minutes late, we suggest skipping the event. It's hard to find us once we start walking, and your host can't answer messages during the event. * This walk is designed for everyone to *move together at the same steady pace* (about 20 min/mile). This format works best when the whole group moves in unison. If you have mobility limitations, we kindly encourage you to find an event better suited to your needs. * Read our [Orientation Guide](https://www.theboardwalks.com/orientation) for full details. * If you enjoy the event, send **[this](http://www.theboardwalks.com/)** to a friend or sign up for our **[newsletter](https://theboardwalks.beehiiv.com/)**. We're in multiple cities with more on the way. 🤠👋 **IF YOU WANT TO GO DEEPER...** [The Board](https://stan.store/ellebeecher/p/the-board) is the next step: a high-trust collective for renaissance people devoted to creating, connecting, and building lives that light us up. * This is a global HQ for people who crave big talk, deep connection, and dream collaborations with people across industries. If the walks feel like a spark... The Board is the fire. Apply [here](https://stan.store/ellebeecher/p/the-board).

You Exist Too Much by Zaina Arafat
You Exist Too Much by Zaina Arafat
[Columbus library link to book](https://cml.bibliocommons.com/v2/record/S105C3351321) Location: The Goat River South 219 S High St, Columbus, OH 43215 Street parking is free on Sundays [Menu](https://static1.squarespace.com/static/686d3ed16745133042482c5f/t/68ff654dbb03b96875430bde/1761568077220/all_brunch-20250311.pdf) Book summary: On a hot day in Bethlehem, a twelve-year-old Palestinian-American girl is yelled at by a group of men outside the Church of the Nativity. She has exposed her legs in a biblical city, an act they deem forbidden, and their judgement will echo on through her adolescence. When our narrator finally admits to her mother that she is queer, her mother's response only intensifies a sense of shame: 'You exist too much,' she tells her daughter. Told in vignettes that flash between the U.S. and the Middle East--from New York to Jordan, Lebanon, and Palestine--Zaina Arafat's debut novel traces her protagonist's progress from blushing teen to sought-after DJ and aspiring writer.

Stop Guessing: A Product Person's Guide to AI Adoption
## 🤝 Host Information A co-hosted event by ProductTank Columbus & Women in Product Columbus 💡 About the Workshop AI adoption is stalling across organizations — not because of a lack of motivation or tools, but because it's fundamentally a behavior design challenge.

Whether you're a product manager, on a product team, or just someone trying to get AI to actually stick at work, you'll leave with a clear picture of what's worth focusing on, what to ignore, and how to drive real, sustained adoption — no guesswork required. 🛠️ What to Bring Laptop: Fully charged and ready to go. AI Assistant: Have your favorite AI assistant pulled up. (Dom will be using Claude, but feel free to use whichever assistant you prefer!) 🍕 Logistics & Perks Food & Drink: Pizza and drinks provided!

In-Person Event: The Answers to Depression & Anxiety
In-Person Event: The Answers to Depression & Anxiety
This is an in-person meeting. At this meeting you will get answers to depression and anxiety. Find out the source of them and how to get rid of them. Did you know that unwanted emotions like anxiety, depression, unhappiness, loneliness, hopelessness, anger, fear, or feelings of irritation don’t just fall on you for no reason. They are not random occurrences that simply happen to people's minds. They are definitely not due to a chemical imbalance in your brain from some nebulous chemical reaction "by chance". Your negative emotions are the symptoms of the painful experiences that you have which are not healed, and which are still affecting you. The effects of these painful experiences are exacerbated by the pressures or difficulties of the other problems in your life. Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life. Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there. This group is created by the Hubbard Dianetics Foundation of Central Ohio and Church of Scientology of Central Ohio.
