Age related hearing loss can actually make you more sensitive to certain sounds. I have difficulty understanding speech but increased sensitivity to sounds including electrical buzzing.

I remember being in school 20 years ago and being taught about scale inaccuracies and the importance of frequent calibration. The thing about weight loss is that you will lose weight if you’re in a deficit. Your daily calorie needs are going to fluctuate a little bit, regardless. Most people don’t keep activity the exact same, sleep the exact same, take exactly the same steps everyday, plus hormones fluctuate, etc. Your measurements don’t have to be precise, just close enough. People have also lost weight with sloppy volumetric measurements, counting out chips, or even eyeballing the amount of space taken up on their plate. MyPlate.gov was rolled out after consumer research found that it works.
