No, that's not a given. You don't want to push people with an already low blood glucose level down to hypoglycemia levels.

Low blood sugar can be a problem not only for diabetics who take too much medicine, but also people with Addison's disease, non-diabetic alcoholics, and people who do endurance sports or very high levels of exercise.

Semi-annual surveys confirmed that during year 03 to year 08 after BCG vaccinations there were no reports of severe hypoglycemia by any patient, even with lowered HbA1Cs near the normal range, and no change in their care as it related to new insulin pumps or continuous glucose monitoring devices. The placebo group of subjects continued to show hypoglycemia events during the same time periods of monitoring.

There isn't a large artery on top of your wrist, where fitness bands use an optical sensor to measure heart rate. The capillaries that they do sense typically lag behind the heartbeat, and have an inconsistent rhythm. A fingertip sensor works much better, as does a chest strap (which is useless if you're hairy like I am). But aside from amusement factor, a wrist band will only give you an approximation of your real heart rate, and it may be quite a bit off in either direction.

Only if you feel the need to track data about your exercising. Frankly unless you are an elite athlete then you really are just tracking that for grins and giggles most likely or are a hardcore fitness enthusiast. It doesn't matter how good a job they do of it if you don't need to track your heart rate.

One only has to look at the waistline of most americans to know that most of them aren't terribly concerned about their heartrates.

Take your kid to a playground and look around. There's no clock. Go hiking or camping. There's no clock. Go to a trampoline park. No idea why they make the clocks so hard to see. Go to any restaurant. Beginning athlete's are most in need of heart rate monitors.

of all the sports that employ this, why reference table tennis? :)

baseball => curve ball tennis => drop shot i'm sure there are other examples, but TT is pretty niche (though fun)

Is there anything that guy CAN'T do?

It seems like Google has made it clear that their work environment is definitively hostile towards anyone who dares question feminist dogma.

Of course, the only way they'll learn that lesson is if they're taken to court over this, for unlawful firing.

Rather than hundreds of millions of vehicles spewing toxic fumes from gasoline combustion at ground level everywhere people live, we'll have merely thousands of power plants spewing toxic fumes from coal combustion hundreds of feet into the air far outside of cities. It's not a great win (yet), but it's still a win.

Now, all of a sudden Koreans are worrying about their elites paying each other off for favours? It's hardly a new thing and no-one important has been prosecuted over these sorts of deals before.

I wonder what has changed?
