Mindfulness Meditation group practice every Wednesday evening at Unity of Gaithersburg. Mindfulness practice is not about achieving some special state of mind; it is more about noticing the experience you are having without trying to change it. This interesting video suggests why you might sit and watch your mind wander off. https://www.youtube.com/watch?v=DmmBF8eTl18 This noticing tends to shift your nervous system from a 'fight-or-flight' state to a more relaxed and receptive state. In this receptive mental state, you begin to see your own experience differently and, over time, see other people and the world differently. Also, it is good for you: "the effect of regular meditation on the cortex was so profound that fifty-year-old meditators had a prefrontal cortex that looked like that of a twenty-five-year-old" [https://www.amazon.com/gp/product/B07PLRZVTT](https://www.amazon.com/gp/product/B07PLRZVTT) Here is an interesting and funny take on meditation by Ajahn Brahm: [https://www.youtube.com/watch?v=TR60RRmXeYs](https://www.youtube.com/watch?v=TR60RRmXeYs). If you arrive on time, there will be an introduction at the beginning, if you arrive late, find a chair and join us. There will be some discussion after. This is a free event, but contributions to the church's expenses are welcome. You can just show up this Wednesday or subsequent Wednesdays.

Whether you're Deaf, HoH, an interpreter, an ASL student, or just want to learn or practice American Sign Language (ASL), we welcome all levels of signers to come join us for an evening of ASL socializing and practice. This event occurs on the first and third Sundays of every month, in the heart of Fairfax County at the Fairfax Wegman's (corner of Route 29 and Monument Drive). We can be found on the upper level, typically near the stairs. We generally start around 7 pm. ASL beginners are welcome, but you should know the ASL alphabet and some basic signs - this is not an ASL class, but the more experienced signers are generally happy to help beginners learn and improve. There is no better way to develop your signing skills than by joining the conversation with other signers. There is a place for everyone to join, learn and practice. Regardless, we are always welcoming so don’t be discouraged to attend; this is very informal and new folks are always welcome. Note, some attendees arrive early and grab some of Wegman’s food for dinner, so you can combine a shopping trip with the ASL practice.

Attendance is $35 (cash, credit/debit card, or ApplePay - paid at the door), which includes water/soda/coffee, bread, choice of a plated lunch entrée, and a dessert assortment. Parking is also validated in the Reston Station garages (3 hours of validation). Join one of Northern Virginia's most successful business networking groups (part of BNI).

The next NoVABeerSec event - "Informal Gathering of Security Minds Over Beer" will be Wednesday, April 29th, 5:30PM til 7:30ish at Aslin Beer Company - Herndon Taproom (767 Elden St., Herndon VA 20170). **Venue for April:** Aslin Beer Company (https://www.aslinbeer.com) - Aslin Beer Co. was founded in 2015 by Andrew Kelley and Kai Leszkowicz. The name, Aslin, comes from the family that connected Andrew and Kai through marriage; they each married a daughter from the Aslin Family. Andrew’s professional background was in finance and consulting, while Kai worked in public service. They bonded over a shared interest of craft beer and home-brewing, which eventually lead to the idea that “We can do this too.” **Additional Info:** We are an inclusive group, so if we missed anyone please let us know or if you want to bring your significant other/spouse please do. We do know there are folks that have changed roles since we last met so please also let us know if we need to add new contact info for people. Have a great week and see you later this month! Cheers, Rinaldi Rampen & Mike McCabe of @NoVABeerSec
