When the telephone was invented, you simply COULD NOT use the device independent of the monopolistic phone company.
When the television was invented, you just COULDN'T stick an antenna out the window and watch your neighbor's 16 mm home movies. You had to use a BROADCASTING company!
I tried to change my Gillette razor blades the other day - I COULD NOT BELIEVE I had to buy expensive "Gillette" razors only!
The reasons why TV, telephones, and even razors simply work, as opposed to being a consumer nightmare, is because they are based on proprietary models and are consumer goods, not hackers' tools. Apple has tiny, fragile devices that it does not claim to be PCs (or PCs for the rest of us).
As others have said, if you don't want an iPad/Touch/phone, don't buy one. Try a Kindle. Oh, wait...
Not exactly. The heart muscle itself never runs in "anaerobic mode", which means without oxygen. Anaerobic + heart = death. Death to at least the part of the heart that is deprived of oxygen, or to the person itself it the area of damage is big enough and/or the heart muscle death includes damage to the conduction system (causing an arrythmia, usually ventricular tachycardia).
Peripheral muscles (extremities) OTOH can work without oxygen, and function "anaerobically" for a limited time, at the expense of build up of lactic acid (the production of which precedes the requirement for oxygen), leading to peripheral muscle cramps and eventually failure.
You can stress yourself during a workout of the legs, say, until they are painfully, crampingly working anaerobically ("anaerobic mode") but it is not correct to say that your body (and certainly not your heart) is running "in anaerobic mode".
Monitoring the heart rate during an aerobic exercise such as running is a way to measure cardiovascular and optimize fitness, as you (and the AHA source you quote) correctly state. The rate of your heart, however, tells nothing about whether your leg muscles are running anaerobically.
You are right. To argue otherwise is Lemarkian. Case closed.
Just because you removed my appendix yesterday does not mean we are evolving ipso facto to an appendixless state. This is true even though we humans *are* gradually phasing out the appendix. In fact, by altering my somatic makeup (by removing the appendix), you are if anything perpetuating the continuing species presence of the appendix, because those whose appendixes are removed will no long die of appendicitis and will therefore breed some more--the presence of an appendix at birth (the genetic endowment) is no longer detrimental.

They're probably just going to monitor heart rate to optimize aerobic exercise. At a certain point if your heart is beating too fast you'll end up in anaerobic mode. http://www.americanheart.org/presenter.jhtml?identifier=4736

Not quite. Mammals: horse > horse goat > goat buffalo, bison > buffalo, bison rabbit > rabbit Fish: snail > escargot It's eratic, or broken, as the original poster stated.
