A guy at the parts counter in Spokane told me 'the computer says it fits' and cost me 3 hours.

Hot take: I thought LED masks were just a fad until a client proved me wrong

For years, I wrote off those at-home LED masks as overpriced junk. Then a regular client, who has stubborn rosacea, brought in her own $300 mask and asked me to incorporate it into her facial. We did a 20 minute red light session before her usual calming treatment. After just four weekly visits, her baseline redness was visibly reduced by what I'd guess is 40%. Her dermatologist even noted the improvement. I'm still not selling them, but it made me rethink my stance on some home tech. Has anyone else had a client get real results from a device you were skeptical about?

I keep seeing articles say the Maya collapse was sudden, but a dig report from Caracol shows a 150-year decline

I was reading the final site report from the Caracol project in Belize, and they detail how population and building work slowly dropped for over a century before the big cities were empty. It makes me think the 'mysterious collapse' idea is more for headlines than facts. Does anyone know of other sites with similar long-term decline data?

Checked a flue in a 1920s house in Tacoma and found a weird old damper

I was cleaning a chimney at a home built in 1920. When I ran the camera up, I saw a cast iron damper I hadn't seen before, shaped like a big flat plate with a center pivot. The homeowner said it hasn't moved in decades. I had to carefully chip away some creosote just to see the hinge. Has anyone run into this specific style and know the best way to free it up without breaking it?

Back when I started, we used to cut everything by hand with a knife and a straight edge.

A few months ago, I got a new cordless floor cutter to try and speed up a big vinyl job in a school cafeteria. I set it up, ran a test cut, and the blade wandered off the line and ruined a whole plank. The rep told me over the phone, 'You have to let the tool do the work, don't force it.' I learned that sometimes the new gear needs a softer touch than the old way of just muscling through. Anyone else have a tool that worked worse when you tried to use it like the old one?

I finally left my accounting job for a welding apprenticeship at 35.

Everyone told me to wait for a 'perfect' time to switch, but after my third missed family event for a quarterly close, I just applied to the union hall. I'm three months into the program and broke, but way happier. Has anyone else jumped into a skilled trade from an office job and have tips for the first year?
