Leaving messages on read is tied to feeling overwhelmed. A study in Computers in Human Behavior found that too many messages, heavy workloads, and time pressure made people anxious and more likely to put off replying, and messages that looked useful got answered faster. Researchers from Sun Yat-sen University, Wuhan Institute of Technology, and Yunnan University started with in-depth interviews about how people handle messaging apps. From those conversations they built a model of why replies get delayed, then tested it with survey data from app users in China. The study was published in 2023. Forgetting to deal with messages, putting off replies, and reading without answering came up again and again in the interviews. The researchers call these negative use behaviors, small ways people push back against a flood of information. Too many messages, too much work, and tight deadlines all raised two feelings: anxiety about keeping up, and a mental resistance to the app itself. Both feelings went with paying less attention to messages and replying later. Messages that looked worth reading interrupted that chain, because when usefulness was high, the path from feeling overloaded to replying late got weaker. People still felt the overload, but useful messages were more likely to get an answer. All the data came from one country at one point in time, so the authors want studies in other countries and over longer periods. In this study, the messages that got faster replies were the ones people saw as useful.

Leaving Montreal … 🇨🇦 Nice quiet lounge to get some work done before boarding, rare enough these days to give @airfrance a s/o 👍 See you soon in Asia 🇯🇵🇰🇷🇸🇬

LeVanta Tech, a defence startup based in Diamondhead, Mississippi, is building HALIA, an uncrewed aircraft that floats motors-off on the open sea, then lifts itself onto three hydrofoils, skates across the surface and takes off without a runway or a catapult. The company says its prototype has demonstrated float, take-off, flight and water landing, with the float-to-airborne transition done in under 60 seconds, while figures such as 30 days on station and 120 nautical miles of range remain modelled targets. It is funded by US Air Force and Navy SBIR Phase II contracts and is covered by a memorandum of understanding signed with Ukraine's defence industry in October 2025.

Leaving 45 lb plates on machines after you're done isn't "courtesy." It's laziness disguised as helpfulness. Not everyone who uses the machine after you can safely move or unload that weight. For beginners, smaller lifters, older members, or someone recovering from an injury, walking up to a machine loaded with multiple plates can be frustrating and intimidating. Gym etiquette is simple: • Use the equipment • Finish your set • Put every plate back where it belongs A machine should be left exactly as you found it — ready for the next person to set it up for their own workout. If someone is strong enough to press the weight, they're strong enough to load it. Cleaning up after yourself isn't optional. It's part of training. Unpopular opinion, but reracking your weights says more about your character than how much you can lift. What's your biggest gym etiquette pet peeve?
