It’s a tech-sensational Sunday, friend! Watch closely during the Daytona 500 today. NASCAR teams are investing $600,000 in 3D printers for pit stops! They’ll be creating custom parts on the fly, from laptop holders (yes, the drivers use laptops) to tubing fixtures. Catch all the action at 1:30 p.m. ET on Fox and Max. Vroom, vroom!

👉 Just one: You can help make the world tech-smarter with me. Use the buttons below the top story to share it with friends or family, or forward my newsletter after you’ve read it. That would be amazing! — Kim

Spring break is around the corner, and Sundays are the best day to book trips, so let’s talk travel hacks. My dad worked for United Airlines, so I grew up on airplanes. I’ve explored 38 countries (and counting!) with plenty more on my bucket list. Let’s get you the best deals!

How to land the best flight deals

✈️ Check for 24-hour price drops: Booked a flight? Some airlines let you cancel within 24 hours for free. If you find a lower price, cancel and rebook. Easy savings.

🔔 Set up price alerts: Google Flights and Kayak will email you when prices drop. The best time to book? One to three months ahead for domestic flights and four to six months out for international. (Note to self: This means next week.)

📅 Fly on the cheap days: Tuesdays, Wednesdays and Saturdays are usually the cheapest. Red-eyes and early morning flights also cost less and are less likely to be delayed or canceled.

🛫 Be flexible: Try Google’s Explore feature to spot budget-friendly dates. Skyscanner’s Cheapest Month tool is neat. Instead of choosing a date, click Flexible Dates and watch the prices fluctuate.

🛑 Hidden-city ticketing (use with caution): Skiplagged finds flights where your destination is a layover, which can save you cash. Just don’t check a bag. It won’t follow you.

I hope these hacks helped you. Now, where should I go next? When you rate this newsletter at the end, let me know in the comments. I’d love to hear your suggestions.

When I was growing up, everyone knew to keep their bones strong, they needed to drink milk. The age-old advice is that it prevents bone loss and breaks.

Get this: A 2013 Harvard study revealed men taking over 1,000 mg of calcium supplements daily were 20% more likely to experience heart problems. It also showed calcium and vitamin D supplements don’t actually lower the risk of fractures in older adults. So, what the heck are we supposed to do?

There’s a better way to keep your bones strong. NativePath Collagen strengthens your bones and helps combat age-related bone loss naturally. Forget the calcium overload — protein could be your secret weapon.

Plus, Paul needs meeting reminders, Victor has 2FA banking worries, Lynn wants her own newsletter, Christine disposes of old phones, Mathew’s Wi‑Fi is terrible and so much more!

Reddit getting paywalled: That’s when you hit a post online and it’s blocked until you pay a membership fee. It’s coming to Reddit, at least for certain content. Reddit went public last March, so it makes sense they’re looking for more ways to make money.

🚨 Deepfakes going to a new level: TikTok owner ByteDance built an AI tool that makes realistic videos of people talking and singing from a single photo. OmniHuman can take an image (half-body or full-body) and bring it to life. Check out this example of Albert Einstein. Snazzy but scary in the wrong hands. And let’s not forget this is Chinese-owned. I wouldn’t hand over any personal pics.

Miracle drug? Wow, this is big. A clinical trial just confirmed semaglutide (the active drug in Ozempic) helps people drink less alcohol. Folks with moderate alcohol use disorder who took a low dose drank about 40% less and had fewer cravings.

🍏 So long, farewell: We’ll get the full scoop on the next budget iPhone on Feb. 19, but the SE 4 is finally ditching the Home button. Touch ID? That’s gone, too. Face ID is taking over. Lightning charging is out, too, making way for USB‑C.

💘 Dating apps are out: My son has been telling me this for years. Folks are still finding love online but through shared interests and hobbies instead. Nate and Jess developed a long-distance relationship playing World of Warcraft. And it’s not just gaming. People are meeting through fitness apps like Strava, too, and social media DMs.

🔪 The short fortune teller who escaped from prison was a small medium at large: A true crime YouTube channel is racking up views, and most people listening don’t realize every “true story” is completely fake. They’re all AI-generated. The channel owner called it “True Crime” because the genre gets the most clicks. Nice ploy, buddy.

AI can you give the right vocab: Say you need to take the car to the mechanic and don’t know what to say. Start with ChatGPT. “My car takes longer to start, and sometimes, there's a lack of power when accelerating. What's going on?" This works for any subject where you’re not the expert!

💬 From Á to Ź: Need to type accents for Spanish words? On Macs, just press and hold the letter on the keyboard. Options for different accents will pop up. For Windows in Word or Outlook, press and hold Ctrl + apostrophe + comma, then release before typing the letter for an acute accent.

Hey, web developers: Have you tried Amazon Q Developer? Think of it as your intern to help write code, create README files and find security holes. There’s a free tier for 50 chats per month, or pay $19 per month for more perks. It’s not a sponsor, but it just caught my eye.

🐕 Ruff, ruff: Sniffspot turns your outdoor space into a private dog park. Some homeowners earn up to $3,000 per month and don’t even have to be home to manage it. I wonder if you have to pick up the poop yourself.

I will never become a flyfishing expert: OK, never say never, but I got sick of seeing ads for them. In Google’s Ad Center, you can browse everything Google knows about you (and delete it), block ads you don’t like and adjust the categories you see. A lovely Sunday activity.

It’s a holiday weekend, and that means sales, sales, sales.

🛒 Time for some couch shopping time: Lots more deals here for your browsing pleasure! Have fun.

🙏 Try: A chatbot for Bible verses. Looks neat, but I wouldn’t confess any deep, dark secrets. You never know what they do with that data.

Protect: Your computer from junk. Jim in Utah asked, so here’s the link to my antivirus and antimalware software pick.*

🦴 Watch: My quick video about how one bonehead delayed a flight for five hours.

Smile! But not too big: Take the perfect selfie for social media. And, yes, LinkedIn is definitely different from Instagram.

Upgrade: To earbuds that sound great and won’t die halfway through your walk. Raycon’s earbuds (20% off) sound just like the expensive pairs,* but with a price tag you’ll love.

For my nerds: A walk through the evolution of eyes from MIT. Neat!

Stop: Fighting over outlets. I love flat outlet extenders that can hide behind a couch or table.

Need some company? Catch the podcast version of my national radio show! I appreciate you being here and all the support you send my way. A favor to ask: Drop a review. In Apple Podcasts, look for Write a review and say something nice. On Spotify, it only takes a sec to give me five stars. Every review helps more people find me and get tech‑ahead.

😆 Back in the day, I had a podcast about bloodsucking arthropods. So weird, but it didn’t take off. That was the end of TickTalk. (Come on! That was funny!)

Psst, in case you missed it, NativePath’s collagen is 45% off with my link.* I take two scoops of collagen a day because there are so many benefits for nails, skin, hair and bones. You should, too.
