I think there's been very little evolutionary pressure to increase lifespan in creatures like fruit flies since despite their short lifespan few of them die from age related causes. I would assume it's pretty easy to increase the lifetime of short-lived creatures in a protected environment, and pretty unlikely that the methods which accomplish this would also extend the lives of long-lived creatures.

What do fruit flies usually die from?

Broken hearts.

Bad autopilot implementations.

Earlier quoted context omitted.

The gut bacteria findings go against the previously held view that antibiotics were the solution to every health problem known to mankind.

It turns out antibiotics are actually pretty awful - they wreak havoc on your microbiome, they modulate your immune system in weird ways, they cause some weird allergies. But they are still way better than the diseases they cure, and definitely better than death!

Yep, antibiotics are the lesser evil. The only thing I really don't agree with is how easily and how much it is used in our food production.

Toxins move up the food chain, and with humans being pretty much the top of that chain we shouldn't be dumping medicine into livestock just to keep them from getting sick.

In a few years we might look back at this period and think: oh, it was at the time when we thought gut bacteria was the solution to every health problem known to mankind. Remember when it was vitamin D?

Maybe one day we'll realize that there is no single factor for good health. Maybe it's Vitamin D AND gut bacteria AND lot of other factors that are even individually different?

In a few years, we might look back at this period and think: oh, it was at the time when we actually thought correlation studies had any value.

Except that they get prescribed a lot, almost as an insurance.

And in some countries, they give antibiotics for viral infections because patients just want them!

Got the common cold? Here's some Amoxicillin!

I think this is very different in that it's something we previously completely disregarded in health outcomes. We consume various things that we know wreak havoc on our gut biome including antibiotics and various residual herbicides, but it was felt that this was mostly harmless as the gut biome did not play a critical role in our physiological condition. Now it's seeming that it may indeed be quite a critical system in the human physiological condition and so it's more of an entirely new field of study than a miracle cure.

I feel as though there is some degree of ostrich-syndrome when it comes to the deterioration of American physical and mental health. Something is causing this change, and most convenient explanations (lethargic lifestyles, internet, etc) do not really work since that would imply a comparable decline in other areas that have also seen such changes, yet the correlations there are spotty at best.
