    I neaten my bathroom every day. Police the water splatters (before they become water stains), lint, soap scum, toothpaste/saliva deposits in the sink, stray hairs, wipe the bowl… And then I deep clean once a week.







  • Sure, but if you’re suffering from radiculopathy (pinched spinal nerve root), the sleep deprivation and increased stress make those interventions more difficult. The article failed to mention inexpensive and free physical therapy interventions.

    If you are suffering from lumbar or cervical radiculopathy (or a slew of other joint pains), check out McKenzie Method therapy. It’s free/freely available, designed to be within reach of anyone, and can be done just about anywhere. Bob and Brad are prolific in providing exercises to get you back into fighting form. Robin McKenzie’s book “Treat Your Own Back” is also excellent.

    Edit to add: a lot of radiculopathies manifest as referred pain, e.g. a pinched nerve in C4-C5 might feel like tightness or pain in the trapezius, under the scapula, in the elbow, or at the extremes, pain and tingling in first and second digits. Sciatica is the the most “famous” of radiculopathies.

    Anecdote: I had a C4-C5 radiculopathy, and it was pushing me into disability territory. The orthopedist wanted to do all kinds of stupid, expensive, invasive shit. I stumbled on McKenzie’s back book and was back at work in two days. I also suffered from piriformis pain for over a decade. It was an L4-S3 radiculopathy. A few minutes of basic McKenzie stretches, and it goes away.






  • What is the benefit of tubeless bicycle tires anyways?

    Tubeless tires can be run at lower pressures without risk of pinch flats, also called snakebites because of the distinctive double hole in the tube. The wider working range of tire pressures allows riders to dial their tire pressure to the riding conditions, whereas clinchers (standard bicycle tires + tube) have much narrower pressure ranges. Varying the tire pressure has all kinds of benefits, especially with multi-surface tires, allowing the cornering blocks to bite into the surface earlier in turns. On gnarly chipseal pavement, the lower pressure means less fatigue, which quickly adds up over some miles. Failing to notice, or being unable to avoid, a pothole won’t cause a pinch flat. You can still dent your rim, but that’s mostly a non-issue with the ubiquity of disc brakes on bikes. On a clincher, you’re guaranteed a pinch flat if you hit something hard enough to dent the rim.

    Tubeless tires provide the feel and higher traction of tubular tires (also called glue-ons, sew-ups) with greater durability, easier maintenance, and easier repairability.

    For regions with goatheads and blackberries, tubeless is pretty much the only way to go farther afield. Tire strips can help, but they deaden the feel, mess with tire dynamics, increase rotational weight, and very rarely protect sidewalls. They are also (usually) horrible to install and can chafe tubes unless installed very carefully.

    In regions without regular street-cleaning, with less frequent tire replacement, and with higher use of tire chains, it’s very common to encounter tire belting and fragments of tire chains. Tubeless bicycle tires are a day-saver. In my own experience, I can now ride those roads where it was previously common to get multiple flats. Before I switched to tubeless, one ride in particular in rural Oregon resulted in 8 flats in 40 miles. And then I was out of patches and spare tubes; day is over, call for a ride. All the flats were caused by tiny pieces of tire belting. I now check my tires once a week to pick out the tire belting I picked up, but I get zero flats.

    Oh, I forgot to mention, it did not clog the valve at all, and it’s also tire sensor safe.

    Our direct experiences are very different. And bicycles don’t have TPS.

    If FaF was actually superlative for bicycles on any metric, we would all have switched long ago. At the very least, some pioneering shadetree bike mechanic would be singing its praises far and wide. I resisted the tubeless tire trend until late 2025 despite having worked on other’s bikes with tubeless, in part because I didn’t feel like building up new wheels. “Meh, everything I have is just fine.” I kick myself for having hesitated. It’s just so much better on all counts.


  • Sealant for tubeless bicycle tires is an entirely different formulation, and FaF is categorically ill-suited for bicycle tires.

    • Fix-A-Flat can and does dry into a lump. Bicycle tire sealant dries out to a powder, and is easy to clean out. Even better, just keep adding more sealant until it’s time to replace the tires.
    • I have seen bicycle rims corroded by FaF, but I don’t know how long it was in there. What I do know is that these bicycles came into my shop because FaF wasn’t sealing the punctures they were getting (goatheads and blackberry thorns).
    • FaF will clog valves, whereas bicycle tubeless sealant may or may not clog the valve; even if it does clog, bicycle sealant is easy to clean.
    • FaF is a temporary fix; bicycle tire sealant is explicitly part of running a tubeless setup and is sometimes used to help seat the tire; FaF comes with propellant and would be pretty awful to use when setting up tubeless wheels.
    • I’m pretty sure (but not certain) that FaF switched to a non-flammable propellant; tubeless bike sealant has no propellant
    • FaF is not designed for the higher pressures in many bicycle tires




  • Idling engines chap my ass. But TINSTAAFL. Auto stop is terrible for engines; the majority of engine wear in passenger automobiles occurs at startup. Also, during auto stop, the catalytic converter cools down a bit, so emissions go up. More wear —> more emissions —> more waste.

    Edit: For my rebuttal, I started digging into this. While the sources I found are still “auto technician says so,” it looks like engines with auto-stop are built for more start-stop cycles. I was operating on outdated information. Automobile engines were/are typically designed for 100k to 150k starts. In trying to find more information about auto-stop, the overall consensus seems that auto-stop engines are designed for >300k starts. Moreover, there seem to be some accounts indicating that exhaust temperature is part of the auto-stop monitoring, which would make sense and keep the emissions controls running properly.

    So, thanks to @borkborkbork, @0ops, and @Janx for prompting me to get updated information.

    But as a bike commuter, auto stop was pleasant in traffic, at least until everyone suddenly started up again and then stomped on the pedal.

    The wholesale gutting of all attempts at environmental protection is an interesting choice for the “protect the children” party. But even as an avid car hater, I’m not sure this is a huge loss.


  • I deeply empathize and sympathize with the challenge. I also failed to choose “congenitally rich” at birth, and I hope to remedy this error on my next iteration.

    But seriously, I grew up very poor and left my abusive home at 16. I was homeless twice. Once in my late teens and again in my mid-20s. Not “crashing on my friends’ couches” homeless, but rather “living in the woods and dumpster diving for food” homeless.

    I bring this up as empathy by way of anecdote, and also as acknowledgement of my immense luck and privilege. I know that reaching a place of relative comfort is fucking hard in our modern environment. What’s an even bigger pisser is that cost of living is stupid, the systems required for modern life are expensive, and the attacks on our attention, focus, health, and well-being are legion.

    So it comes down to: is your position yet painful enough for you to want to do something about it?
