Primarily because they're hard to take accurately. Using calipers takes training; the bathroom scales which report body fat percentage are using an approximation based on conductivity which have varying results. BMI is quick, and I agree not a very good measure, particularly if only used on their own. For example, lean, muscular people can have BMI values which, outside of context, place them as morbidly obese. But, because they're expedient, they've continued to be used.
Always check to see if a place near you will accept furniture items as a donation. (Goodwill, Salvation Army, etc.) If nothing else you get a tax credit for the donation.
Can we get a citation for the toxicity of ABS? My Google-fu is failing me as I can only find articles that say the fumes can cause minor irritation when inhaled or in contact with the eyes.
"The higher temperature ABS-based printers had total UFP emission rates nearly an order of magnitude higher than the lower temperature PLA-based printers (1.8-2.0 10^11/min compared to 1.9-2.0 10^10/min)."
"Primary gas-phase products of ABS thermal decomposition at very high temperatures have been shown to include carbon monoxide and hydrogen cyanide, as well as a variety of volatile organics (Rutkowski and Levin, 1986). Exposure to thermal decomposition products from ABS has also been shown to have toxic effects in both rats (Zitting and Savolainen, 1980) and mice (Schaper et al., 1994)."
It's not about checking in. Obviously I had to provide an ID to every hotel I've checked in (though reportedly Richard Stallman manages to avoid that too). It's about not having to upload a profile photo to be able to use the damn app. It's the only app I've seen (including Facebook itself) that insists on doing that, and it makes zero damn sense.
Just to clarify there are toxins that will bioaccumulate such as heavy metals, however simply including meat/dairy/eggs in your diet will not cause this.
