Just to clarify, the goal was not to seek ways to control blood sugar levels. The goal was to eliminate "trigger foods" that threw the body's systems out of whack.

My personal feeling is trying to control BLS via not-diet-related activities is masking the real problem - a person's sensitivity to certain foods. We were simply trying to see what would happen if we simply stopped eating our trigger food - and the results have been positive. We have an insignificant sample size, so I'm only reporting this in case others want to experiment.

Thanks for the link, BTW.

I also lost about 30 lbs, with no exercise, by changing my diet to a low-carb diet. But I used a closed-loop feedback for food selection for less than US$20.

I (and several others) purchased a blood sugar meter. Basically, we would check our blood sugar levels (BSL) at 1 and 2 hours after eating. We all found that some foods would take us up to 120 (the upper limit for our experiment), but some foods blasted BSL up to 200. Avoiding foods that triggered high levels caused us all to lose weight, feel less hungry, and we snacked less or not at all. All of us saw significant-to-radical improvements in our health. The real surprise is how many foods affected some of us, but not others. The more we compared notes on food, the more we realized it to be dependent on the person's response. Foods that affected all of us tended to have wheat, corn and related by-products.

I share this, hoping others will give it a try and report back.

The idea of a one-size-fits-all diet makes as much sense as a one-size-fits-all shoes and clothing. I'm convinced we need to take advantage of the feedback tools available and customize your own diet, based on your body's reactions.

You really should learn a bit about polycarbonate - better known as Lexan (that's the Sabic trademark for PC). It's extremely durable, very shatter resistant, highly UV resistant,

Yes, I should. I've only used it since the mid 1980's - back when it was "GE Lexan". ;D But I won't claim to be an expert in PC.

Help me understand. You say "highly RV resistant", but the Wikipedia article you reference says RV resistance is "fair".

And from here: http://en.wikipedia.org/wiki/C...
"Crazing occurs mostly in amorphous, brittle polymers like polystyrene (PS), acrylic (PMMA), and polycarbonate; it is typified by a whitening of the crazed region."

So I will admit to a lack of expertise with PC, but what I've cited agrees with my own experience. I'd certainly appreciate more data, if this is your field.

". PC tends to craze (small cracks) when exposed to UV."

^This^ you have wrong.

While I won't argue that PC is the best material, that 'craze' comment is ... crazy.

I'm open to the idea that I'm wrong, but you've not done anything to support your assertion. I'm also open to the idea that you are a troll. Let's seek a third opinion on the subject.

From http://en.wikipedia.org/wiki/C...

"Crazing occurs mostly in amorphous, brittle polymers like polystyrene (PS), acrylic (PMMA), and polycarbonate; it is typified by a whitening of the crazed region."

I could still be wrong, but there does seem to be some evidence that I may be right.

I'm a motorcycle rider and racer for over 40 year. This helmet scares me.

First, this little detail: "The “highly weather resistant” helmet is made of a “lightweight, aerodynamic” polycarbonate shell, says Skully Systems."

Polycarbonate - OK, that's the material used in low-end helmets (sub $200). In the $300+ category, we have fiberglass and carbon fiber. PC tends to craze (small cracks) when exposed to UV. I've seen a PC helmet crack in half when it fell off the bike and hit the concrete. Just from the material, I'm not interested.

Second - When I watched the video, I found the lower right display too distracting. Riding a bike in traffic, you never know when some idot will run a stop sign, or pull out in traffic. You need to be able to pick up any movement as you scan for threats. This adds distraction. Distraction on a motorcycle kills. Kills you dead.

Third - Did you see how most of the testimonials come from non-riders? There was a "tire expert" (WTF is that?) and only one racer/builder. So I think this is a bunch of tech guys putting together a somewhat-cheap helmet, as a way to sell cool tech.

Over time, this may (should?) evolve into something that works well. But I fear this will turn into the motorcycle-equivalent of the texting-while-driving problem.

I suspect Amazon sees the smartphone as a portable checkout terminal. Rather than leave it open to any competitors, they want to own the OS and get a peek at what you're looking for. It's also a consumption device, and is the hook to selling movies, books, etc. It may be the case that they really don't want to be in the smartphone business, but fear what a competitor might do.

I never had the cruise control malfunction again, but I could repeat the brake issue. Yes, these are two separate issues. But the brake issue prevents the driver from being able to stop the car.

When the car took off (I was on an almost-empty Interstate highway in Texas), I tried to brake and couldn't move the pedal. I put both feet on it and pushed as hard as I could. In the gym, I could push 600 lbs on the leg press. I could feel the pedal arm flexing under the pressure, but it would not move downward. I regained control of the throttle when I shut off the cruise control - leading me to believe the cruise control is at fault.

I demonstrated the brake problem to the dealer. They replaced the master cylinder assembly. As I drove away, someone pulled out in front of me and I could not stop for several seconds. Once again, the turbo was generating positive manifold pressure and the brakes would not move. After the manifold pressure went negative, I regained brakes. I took it back to the dealer. An older mechanic took a look and he said the check valve was worn. Once replaced, the problem vanished.

Summary:
Event 1 - runaway acceleration and zero brake
Event 2 - zero brake on boost
Event 3 - zero brake on boost.

BTW - I have raced motorcycles and cars for years, so I was quite comfortable with the car going fast. Being alone on a sunny day with no curves in sight gave me plenty of time to ponder the cause. I knew I could turn the engine off, so I wasn't in much danger. I was able to evaluate all the suspected causes. Feet on the wrong pedal? Nope. Floor mat or stuck linkage? Nope - it was easy to move and quite loose. The only other thing connected to the throttle butterfly was the cruise control. That's when I tapped the brakes - and discovered it wouldn't move. That's when I realized I was dealing with two faults. Glad I had a dashboard switch to shut down the CC. I was pressing the brakes, and suddenly it started to give slightly. I noticed turbo boost had just gone negative. I hit the gas, built up pressure, and sure enough the brakes wouldn't budge. So that part was very repeatable.

Nearly all the Audi issues were old people hitting the wrong pedal while parking.

And how do you know that? That was the theory Audi suggested - blame the drivers.

Your issue was unrelated to the focus of the issue at the time.

Not at all. I owned the car. I saw the 60 minutes report. People claimed the car "suddenly took off" and "could not budge the brake pedal". This was the exact behaviour that my car exhibited.

Audi claimed (as did others) that they must have hit the gas pedal, and thought it was the brake. That is quite logical. And I'm sure that happened in some cases. But I also know my car did exactly what 60 Minutes claimed.

Interesting that you'd believe a government agency, rather than someone who actually owned the car, had the experience, and analyzed it. You link, however, was crap. He writes:

"When I first heard about the Audi “sudden unintended acceleration” segment on CBS’s 60 Minutes in 1986, I knew instantly that they were blowing smoke. Literally."

So he made up his mind instantly. Well, he's wrong. When my Audi 5000T was on positive pressure (turbo boost), high pressure would leak past the check valve, preventing the brakes from being applied. His statement that the brakes would override the engine does not take that into account.

Money is the root of all evil, and man needs roots.
