Those are manta rays.

BMI is generally useful as a form of shorthand for whether somebody is a healthy weight. Body composition, specifically body fat percentage, matters more. Bodybuilders often fall into the obese category for their height but you generally wouldn't call them fat.

The original BMI calculation has received criticism for classifying shorter people and taller people incorrectly. Shorter people end up with a BMI that is proportionally too low and tall people proportionally too high.

You're fairly tall, but still fall squarely in the overweight category with the new calculation (https://people.maths.ox.ac.uk/trefethen/bmi_calc.html). Even with the new calculation, it's still a shorthand method and won't be accurate in all situations.

For a more accurate picture of whether you may want to consider losing weight, a Dexa scan will determine you body fat percentage. General guidance is <20% for men and <25% for women.

Pro se means they're representing themselves. Probably because of no money.

The linked page uses the Mifflin-St Jeor Formula which appears to have been published in 1990. As someone acquainted with eugenics but not how BMR calculations play a role, could you share some I formation on how the two are related?

The residue left over after boiling water is probably mostly calcium (if white) or iron (if orange/brown). Both are from dissolved minerals in the water source. If you need to clean anything stained by either, vinegar should dissolve the minerals with minimal effort. I'd avoid vinegar on anything stone (like countertops), as some types of stone will dissolve in the presence of acid.

I (distantly) knew someone who was cutting grass on an incline adjacent to a pond. The lawnmower flipped, and it pinned him in the pond. He drowned in a foot of water and was sober.

People misjudge things all the time. I would guess it was a combination of distraction and/or non-ideal terrain (slope, dropoff, or combination).

Franklin might have won the prize, had she not died 4 years before the prize was awarded. Rules forbid the Nobel being awarded to the deceased.

The penguins under car is at a blue penguin colony in Oamaru, New Zealand. Visited there in March. Might not be that exact format.

Walk-in coolers/freezers are giant Faraday cages. You can't get wireless in or out, so it'd need to be wired.

They can't always be recycled, but they usually can be.

It's rampant click bait. I try not to reward the behavior with clicks, but sometimes I'm genuinely interested in the topic. This is not one of those times.
