That WHO study is highly problematic. It has some fairly serious methodological flaws. It’s been disputed by the FDA. It is biased due to the panel comprising:

eight WHO panelists involved with assessing safe levels of aspartame consumption who are beverage industry consultants who currently or previously worked with the alleged Coke front group, International Life Sciences Institute (Ilsi).

To specifically answer their question: No. There is no state that will allow your family to euthanize someone who currently objects, just because that person, while younger, signed a will stating that was their wish.

Just because a slur appears with a definition in a dictionary, does not make it acceptable. And maybe it was acceptable at one time, but things change.

Because the major export product of the United States is American culture. UFO/alien abduction/government cover-ups are kinda baked into American popular culture at this point. Just the idea that the government is simultaneously incompetent yet able to successfully hide far reaching evidence of alien visitation is as American as baseball and apple pie.

I’ve no doubt people are looking up at the night sky all over the world and seeing things that they think are possibly alien craft. I’ve also no doubt that there are stories and folklore about abductions in every country on earth. But American culture is insidious and infects just about everything. This forces every other event to be reframed in reference to the American UFO phenomenon.

This would be kinda fun to play with from a “game theory” standpoint too. Unscrupulous people could attempt to maximize their pizza consumption and minimize their capital investment by claiming to not be very hungry and being willing to eat the most common toppings.

Perhaps the app could have a function at the end to “rate” the participant diners? You could pass your phone around one more time and people could assign a “trustworthiness score” to one another.
