Why does nobody talk about how chain lube attracts dirt way more than it should?

I had this customer last month, a guy named Dave who rides 20 miles every weekend on gravel. He came in complaining his drivetrain sounded like a coffee grinder. I took one look and his chain was caked in this black gritty paste, like the lube turned into sandpaper glue. He told me he always applies it wet and lets it sit overnight before wiping. I asked how much he uses and he said 3 full squirts per link. So I showed him how 1 drop per roller plus a 5 minute wipe down cuts the grime by 80%. He looked at me like I was speaking alien. Has anyone else noticed people just dump lube on and hope for the best?

That client who argued with me about SPF in July

I had this lady come in back in June for a facial and she was maybe 55 with some serious sun damage. I recommended a basic zinc SPF 30 and she literally laughed at me and said she didn't need it because she 'tans easily'. I tried to explain that tanning is still damage, but she cut me off and said her dermatologist told her SPF is a scam. I just stood there with my spatula in my hand not knowing what to say. She ended up buying a $90 serum instead and walked out. Has anyone else had clients just completely ignore science like that?

Question about truing a wheel on a rainy day in Portland

I tried truing my rear wheel after riding through some wet streets last week and the spokes kept pinging weirdly, has anyone else had trouble with moisture messing up spoke tension?

Old timer told me to wet my bricks before laying them in summer heat

I was working a retaining wall job in Phoenix last July and this retired bricklayer named Dave told me to soak my bricks in a bucket before laying them. I tried it on one section and the mortar held way better than the dry bricks I used on the other side. Has anyone else found that wetting bricks helps in hot weather or is it just for certain types of clay?

I just found out the first computer bug was a real moth stuck in a relay, saw it in a museum in Virginia

Finally got the hang of my rock saw after a year of bad cuts

I was always getting jagged breaks on my agate slabs until I watched a guy at the Tucson gem show last month. He was using way less pressure and letting the blade do the work. I tried it on a piece of Lake Superior agate yesterday and the cut was perfect. Anyone else take way too long to figure out a basic tool trick?

Update: A single wrong turn in the Wind River Range turned a 3-day loop into a 5-day survival test

My buddy and I missed a faint trail junction near Lizard Head Meadows, adding 15 miles and forcing us to ration our last two energy bars. Has anyone else had a simple navigation error completely rewrite a trip?

Found out the oldest rock on Earth is in Canada and it's over 4 billion years old

I was reading an old geology textbook from the library and it said the Acasta Gneiss in the Northwest Territories is about 4.03 billion years old. That number just stuck in my head. I always figured the oldest stuff was way younger. Makes you think about how much the planet has changed since that rock first formed. Anyone know of a good documentary that shows that area?

Spent three hours trying to get a stuck seatpost out of an old steel frame

It was a 1990s Schwinn frame I picked up for a project. I tried a ton of penetrating oil, heat from a hair dryer, and even clamping the post in a vise to twist the frame. What finally worked was mixing acetone with automatic transmission fluid and letting it sit overnight. The next morning, it came out with two light taps. Anyone have a better method for a really stuck aluminum post in a steel frame?

Serious question, has anyone tried a full sous vide prep for a busy Friday night?

I set up six circulators in my kitchen in Chicago to handle all our proteins, even the fish. The result was a line that moved twice as fast, but the sear on the steaks was a bit flat without the usual pan fond. I learned you can't skip the old school sear station, even with perfect internal temps. What's your fix for getting a good crust when you're leaning hard on sous vide?
