Oh shit looks like you got em'

Thanks! Both look like very decent studies so I am not certain where the difference comes from. I suspect that the division into age brackets, or averaging across all of the them may be the cause. Either way, it seems that the effects of being slightly overweight are barely statistically significant. The more you know

After some cursory research ([1] among other meta-analyses), this does not seem to be true below the age of 80. Could you cite a source?

I don’t know a single person who consumes milk because they think they require it. They just like the taste of dairy products.

The subsidization is an issue imo, but I don’t think people are as brainwashed regarding milk as you assume.

Rotary engines were never used for helicopters AFAIK. Maybe there are some niche designs

Yup, I know, it doesnt check out at all, you wouldn’t put a rotary on a helicoptor. But “rotary” engines were indeed used on aircraft, since they also refer to a radial cylinder configuration where the engine housing moves and the axis is fixed. So I think it’s likely they were referring to the common WWI plane engine. I didnt think of a wankel at all till you mentioned it! Interestingly enough, modern wankel engines are also sold for helicopters.

I’m a little confused, aren’t they just referring to aircraft rotary engines with the cylinders arranged radially? Or what’s the triggering part?
