Phoenix could get about 3 inches of rain by Tuesday... that’s around 40% of what they normally get in an ENTIRE year. A deep storm system out West is pulling a surge of moisture into Arizona and the Four Corners starting this weekend. Sunday will be the peak, with a high-end flood threat in the San Juan Mountains near Durango, where the ground is still soaked from last week’s flooding. Much of Arizona is in a flood risk too, as the rain will funnel quickly into canyons and desert washes.

Great Q from @HankFrank ... Since low resting HR is linked with #afib occurrence, is it bad to have a low resting HR? Short answer: No, it's not bad to have a low resting HR. In fact, it's a very good thing for your long-term health! Longer answer 👇 By itself, a low resting HR isn't a problem. It becomes a problem when it it paired with pro-arrhythmic substrate in the atria, i.e. "damaged" tissue that can generate or poorly conduct electrical signals. When you pair the 2 - low resting HR + damaged tissue, the increased time between beats gives the damaged tissue the time to "get up to mischief" This is especially the case when the vagus nerve is particularly active/dominant suppressing the normal sinus rhythm - i.e. when an athlete is unusually tired and in "recovery mode". So, how do we prevent? 1/ Don't damage the atria in the first place! Don't hang out in those high intensity zones with sustained high pulmonary pressures. They are not necessary for the positive cardiac adaptations that we seek, i.e. the majority of your training time should be Zone 1 - Eazzzy. 2/ Don't get too tired. Try to avoid those situations where the parasympathetic nervous system is overactive and the Vagus nerve is called into play to shut you down, i.e. rest before you need to. ###### My "train easy" message isn't for my own health; it's for yours. I've already made the mistakes so you don't have to. Don't be an idiot like me. Learn from them.
Interesting discussion. I've always understood my low resting HR to be a natural adaptation to years of endurance training, rather than something I'm actively trying to achieve. Alan- is there actually anything an endurance athlete can do about this, or is it more about being aware of the potential risks and monitoring for issues?

A 20-year-old woman was sitting in a car stopped at a red light when a motorcycle hit her from behind at about 124 mph. The bike weighed roughly a quarter of what her car did, and it still hit with the same energy as her car slamming into a brick wall at 62. This was in the city of Luhansk back in March, a little before 10pm. Russian outlets say the rider was 18, on a Yamaha R6, and estimated his speed from the footage at around 200 km/h. She was in the passenger seat of the second car waiting at the light. Here's how the math works. The energy something carries goes up with its weight, but it goes up with the square of its speed. So if you cut the weight to a quarter and double the speed, you end up in the exact same place. An R6 with a rider on it is around 575 pounds. The Lada she was in, a little Russian sedan, is around 2,300. At 124 mph that bike was carrying about 400 kilojoules, if you want to check my math, which is what the Lada would be carrying into a wall at 62. And all of it hit one spot. When a car hits a wall, the whole front end soaks up the impact. A motorcycle is about 27 inches wide at the handlebars, so everything got jammed into one narrow strip of the back of her car. Rescuers had to cut her out with hydraulic tools. Her car went from sitting still to roughly 22 mph in a fraction of a second, from behind, with nobody inside expecting anything. You might notice her car's taillights look dark in the video. Honestly, it wouldn't have mattered. At 124 mph you cover about 180 feet every second. Even if he reacted in one second flat, he'd travel 180 feet before touching the brakes, and a sportbike braking as hard as its tires can handle needs around 500 more. That's more than two football fields. He was almost certainly out of room to stop before he ever showed up on this camera. He wasn't out there alone, either. Russian outlets say another guy on a motorcycle was riding with him, and that rider made it through the same intersection fine. The 18-year-old died at the scene. She was hospitalized with multiple fractures, including her spine, and later reports out of Russia said she died in intensive care. However you feel about guys who ride like that, I keep coming back to her. She did the thing every one of us does a dozen times a day, stopping at a red light and waiting for green.

What has parity has wrought, Week 8 edition ,,, --Kentucky, after 8 weeks, leads the SEC after beating Vandy. --There are 3 undefeateds— one of them UCLA is the only undefeated team among the Power 2. Miami and ... Utah are the others. --That mushroom cloud you see over Eugene is Oregon being knocked out of the national picture by Illinois. The preseason no 1 in some quarters is now 4-3. --New Mexico has the nation's no 1 scoring defense after beating North Dakota St 21-13. The Lobos lead the Mountain West and are in the thick of the g6 playoff berth chase. Ticket manager/coach Jason Eck, a hot coaching property, and his Lobos played before the largest unm crowd in 21 years. --No 25 Arizona controls its own destiny in the Big 12 and, consequently, for a playoff berth. --Per CBS Sports, the last time FBS had 3 or fewer undefeated teams by OCT 24 was 1977 -- the year before FBS was created. --Wake Forest is 6-1 having won four Power Four games on the road.

France is learning why Egypt, Jordan, and Kuwait no longer accept Palestinian refugees…I think it's because they're Islamophobic.

If you would like to witness genius, watch and listen to this.
Being an exceptionally talented musician is one thing. But to stand before such high-caliber fellow musicians, a large audience, and cameras—all while remaining composed, communicating skillfully and effectively, showing genuine enjoyment, and staying focused on the creative process—that is what truly amazes me.

This is the heartbreak that is so often ignored. When boys play girls’ sports, the boys get institutional support and sympathetic media profiles, while adults in charge congratulate themselves on their virtuous ability to ignore reality. But girls are left abandoned on the sidelines, grappling with a devastating but unmistakable message: “You don’t matter.” States like Washington will toss girls’ fairness, safety, and opportunity aside the moment it interferes with the interests of a boy who claims to be a girl. This isn’t just wrong. It’s a deliberate decision to treat girls worse than boys and demand sacrifices from them that boys don’t have to make. This is unlawful sex discrimination under Title IX. That’s the argument we made in a recent application to the Supreme Court. On behalf of our client Kallie Keeler, we asked the Court to stop this unlawful discrimination and make Washington state give her a fair and safe playing field so she can play the sport she loves. This scene just shows several more human reasons why the Court’s action is needed.
