Making a lower-cost iPod Shuffle alternative to the Apple Watch is almost inevitable with a $279 price floor for an Apple Watch (Series 3), and Fitbit trackers proving the strength of the market for lost-cost fitness-focused accelerometers (Fitbit Ace $99). But what if this was not only a low-cost alternative, but also a unique companion product to the Watch and AirPods? What novel uses and measurements could such a “Shuffle” device make?
Consider that having two accelerometers (Watch + Shuffle) would vastly improve:
- Sleep monitoring
- Excercise monitoring
- Fall detection
And what if the Shuffle could also be placed on the ankle? It could improve all motion measurements through redundancy but also enable new analysis:
- Pace analysis
- Gate analysis (biometric)
- Choreographic analysis
It would not be difficult for such a device to quickly learn where it was placed, allowing you to use two devices on both wrists or move them to both ankles (one could be a watch!), or a wrist and an ankle for different activites (e.g. opposite lims & sides for optimal pace analysis).
The features of such a device could be very minimal to keep the price low (for both stand-alone and companion purchases):
- High precision motion detection
- Haptic notifications for sleep wake, etc.
- Minimal light array for power level, etc.
- Inductive charging
What would be the big win for companion use with Airpods? A true Shuffle-like music player? Possibly. Perhaps some type of voice programming or activity feedback?
Overall, this product would be very Apple-like because it has a singular function but very many uses across many markets.
- Low cost fitness tracking (kids, elderly, developing markets)
- High precision fitness tracking (athletes, coaches)
- High precision motion tracking (health safety, choreography, biometrics)
For price, we’d like to see $99, but I expect $119-149.
There’s a hidden story behind the groundbreaking Zetia/Vytorin Study. Just as important as the confirmation of the effectiveness of the new drug ezetimibe is the more general result that lowering your LDL (bad cholesterol) is good for you.
Huh? Didn’t we already know that?
You may be as surprised as I to learn that the medical guidelines for prevention of heart disease and stroke do not say you should lower your LDL – they say you should take statins. It’s a rather subtle but very important difference. Statins lower your cholesterol but also have anti-inflammatory effects which cannot be readily separated in a typical study. This new study showed the addition of the second LDL-lowering drug (combined as Vytorin) worked better than the statin alone, giving direct evidence for the reduction of heart attack and stroke risk. This drug decreases the uptake of LDL in the gut so other approaches that reduce LDL intake or absorption are likely to be beneficial as well.
I first learned of these narrow guidelines from my doctor in her response to my own approach to lowering LDL. In addition to my low-dose of statin I added a collection of other supplements that are known to reduce LDL (plant sterols/stanols, fiber, garlic). When I conveyed this to her, she said those are fine but if you forget to take any pills (she knows me well) don’t forget to take the statin. “Why is that?”, I asked. “Because I have no medical evidence that lowering LDL alone is going to protect you from a stroke”, she said. Before yesterday, that was true.
So although this study will have a huge impact on Vytorin sales (thankfully off patent in 2016), the far more important result will be new medical guidelines for lowering LDL opening the way for the prescription of other preventative treatments, including drugs, supplements, and diet.
From an article on a Fitness Instructor’s stroke
Fortunately for Jessica, she woke up the next day with feeling in her left leg and few other symptoms than a little grogginess and fatigue. While she had no previously known medical issues, doctors discovered what they believed caused Jessica’s stroke as a PFO, or patent foramen ovale, a small hole in heart that had been undetected all her life and a blood condition called Factor 5 Ledion [Leiden], making her more prone to clotting. Jessica’s team of physicians, have recommended she undergo surgery to close the hole in heart, which she will proceed with this spring and she is taking an asprin a day to regulate blood clotting.
The frequency of the congenital heart defect patent forman oval (PFO) is between 20-30% based on post-mortem studies of normal hearts. The most common Factor V Leiden mutation related to thrombosis has an occurrence of 4.4%1 in Europeans and Caucasions (one of the most common monogenic disorders in the Caucasian population).
Combining those gives a range of 0.8% and 1.3% for having the condition and the mutation. This is surely an oversimplification of the probability, but this seems remarkably high, and could combine with other factors to increase the risk of blood clots. Since her doctor recommending heart surgery, she may have two copies of the Factor V disease variant or other unmentioned factors.
Earlier PFO estimates were 10-15%. Recent higher estimates draw suspicion about this as a causative factor for embolisms. Here’s a counterpoint on the “indictment of the PFO as a source of embolic stroke”.
