they do need more power to maintain speed over ground.

Not exactly true. There is an optimum airspeed and power setting for any aircraft (and weight). Pushing it harder to go faster tends to be inefficient. What one needs when flying into a headwind (lower ground speed) is more time and fuel.

Hasn't this been known for some time?

I think so. Research dating back a few decades has associated cetacean melons with the echolocation function, including some species ability to shape this organ. The purpose of such shaping has probably been understood, as some advanved sonars use similar techniques for beam forming and impedance coupling.

poor Nutrition.

Unlike the poor of many decades ago, today's poor seem to get sufficient caloric inputs. Far too much, in many cases. But they are eating the wrong stuff.

Don't start with the 'poor people can't afford healthy food'. For what they spend stuffing their faces with McDonalds, it is possible to eat very healthy. If one isn't lazy and makes an effort to select and prepare healthy food. So, poor people don't have the time to cook? Maybe, but try taking the pop and snack machines out of a high school and replacing them with healthy foods (thus eliminating the argument about preperation effort) and the fat bastards will raise hell.

Poor, fat people are going to be poor and fat. It's a part of their culture.

I choose to worry about things that are more likely, like identify theft.

So putting back doors in encryption software is OK when done for national security purposes. But bad when hackers exploit these same engineered weaknesses to steal your personal information. Leave your front door unlocked so the police may more easily conduct searches. Never mind that the incidence of burglers cleaning your house out will be orders of magnitude more common. And don't forget that Snowden was an anomoly only in that he forwarded data he absconded with to the press. The NSA/FBI/CIA is full of "contractors" that slip copies of data to buddies in private enterprise for purposes of industrial and commercial espionage.

Our civil rights take a back seat to the needs of law enforcement to manage the populace for the benefit of the elite.
