<p>Indeed. But remember a PE firm has economies of scale because they own many vet practices. They can negotiate better rates with suppliers than you can, and better payment terms. Maybe they even own some of those suppliers. They can divide their advertising costs by all the practices they own, whereas you can't.<p>Even if you were willing to be as ruthless as a PE firm, raising your prices and sacking half your staff, and even if you were somehow an expert in financial engineering and business optimization, you still won't make the business as profitable as they can.</p>

<p>If you start your own veterinary practice, and eventually build up a steady stream of happy customers, then sooner or later the PE firms will come knocking on your door, too.<p>Imagine you're drowning in student debt and worrying about keeping your business afloat, when someone offers you $5M, and says you'll still get to work with animals, which you love, while they take care of the financial and business side, which you didn't enjoy. It's a no brainer for most people.</p>

<p>Porsche is famous for underpromising and overdelivering.<p>For instance they claim a 0-60 time of 2.4s for this car. Car & Driver independently tested it and achieved 2.1s. They also claim 298 miles of EPA range (mixed highway & city driving). Car & Driver worked out 300 miles at a constant 75 mph (which is harder on an EV than city driving.) On the base model, which claims 303 miles range, MotorTrend achieved 350 miles of pure highway driving.<p>Pick any Porsche and you'll see that they lie to make things sound worse than they really are.</p>

<p>Had this done too to cure PVCs - a irregular heartbeat that wouldn't have killed me, but it did lead to an enlarged heart and low energy.<p>I remember feeling <i>great</i> during the procedure thanks to whatever meds they gave me. I could watch them on a screen threading the wire in through my femoral artery all the way up into the inside of my heart. Then I felt the exact moment I was cured. The irregularity I'd known my whole life just changed rhythm. Then they injected some stuff to stress test the heart at high and low speeds. 24 hours later I was back home.</p>

<p>My Mach-E came with CrossClimate2 tires and I am not impressed. I've accidentally lit up all 4 tires under hard acceleration on a dry road, despite 5000 lbs pushing them into the ground and some amount of traction control still active.<p>I have a lighter sports car making similar power, on Michelin Pilot 4S summer tires. That car just grips and goes with barely a squeal. Good summer tires also have far better wet performance than CC2s, and they provide better feedback.. you feel more planted and in control.<p>I am impressed overall with the CC2's ability to be a true all-rounder that is usable in snow, but it is still an exercise in trade-offs and it'll never be as good as any purpose-built tire is at its purpose.</p>

<p>My car (from VW Group) came with Active Lane Keep. It detects when you're drifting out of your lane and steers you back into it. Sounds great in theory.<p>Except that in the US, if you're cruising in the right lane then every time there's an exit it will actively steer you towards the concrete median between the lane and the exit. I don't understand how this feature was signed off on. The risks outweigh the benefits, in my opinion.</p>

<p>Bonds only give you certainty to the extent that inflation remains certain.<p>Stocks generally rise with inflation, whereas bonds continue paying out the same nominal amount, which buys you less over time.<p>As a retiree I'm 50/45/5 in stocks/bonds/cash, having opted for a conservative portfolio. The stocks are the only reason I haven't lost buying power. But the bonds have performed so poorly that I've barely kept up with inflation despite the amazing bull run in stocks.</p>

<p>As someone who is currently going through the diagnostic process for MCAS with a specialist:<p>A negative Tryptase blood test doesn't mean you don't have it, it could just be that you're not having an active flare-up at the time. So they also prescribe high doses of H1 and H2 blockers and then you report whether symptoms have improved across 2 or more organ systems after a few weeks.</p>
