The very first thing I thought of upon reading your comment "The list of things tried so far to resolve the issue..." was "What about a big lighted 'x'?" then I clicked the link.
Exactly my question. It's 9000+ feet long. Put a lighted red X on it every 1000 feet. Or, maybe Xes aren't the answer, but there must be some technique to produce a startling visual warning.
It's probably a situation like Chesterton's fence. There are probably good reasons for not having the Xes. At least I hope so, I hope it's not just "that costs money and then we have to maintain it". The money can't be an issue. How much would 500 or 1000 deaths cost? How expensive are all the other proposals which have been mentioned? Those aren't cheap either.
Indeed, the article does not give any reason for its removal, other than the fact that it was removed. My guess is that it was in disrepair and/or they deemed it ineffective since there were landings in the years preceding the removal.
It does plane detection and can place a 3d object on that plane, scaled accordingly. You can move the phone around the plane (floor, tabletop, etc) and the object stays fixed as if it were physically in that place. The 3d object is also textured and takes into account ambient lighting to shade it. The result is actually rather impressive!
While cluttered and busy, yes, this shows all possible complications on the watch face. You can choose a very minimal display to this and everywhere in between.
Calorie restriction has shown anti-aging benefits as well, does metformin mimic this by restricting glucose/calorie absorption? Does this mean you can have your cake and eat it too?
Intermittent fasting has been shown in a few cases to exceed the benefit of caloric restriction (and it's generally easier to follow: http://www.pnas.org/content/100/10/6216
I mention that because the cytological benefits of IF are also accompanied by well improved glucose regulation metrics. There's a good chance that those changes are at least partial drivers for the overall benefits.
I have to wonder about the "findings" regarding sleep of 7 hours being a causation for a lower RHR. Could it be that the cohort of those who are getting up early to exercise regularly are trading an hour of sleep in order to do so? To assume that "too much sleep is bad for you" seems incorrect given just the aggregate of all data with so many other variables.
