I know you’re joking, but possible causal path here:
People with Alzheimer’s lose ability to use stove -> eat simpler less involved breakfasts -> eats less eggs
You can, but people don't as a general rule. It's a traditional food prepared traditionally. And importantly, another thing early Alzheimers cases don't do is learn new cooking hacks.
Works surprisingly good indeed. Just get a bowl, stir some eggs, add seasonings of choice and pop it in. Be sure to stop the microwave on time, because the mixture expands a lot.
Joking aside, (and I speak as someone who has lost 2 close members of my family to dementia), as soon as people start to experience any form of dementia, there is a sort of coping mechanism that kicks in where they stop doing “complex” things as much as they used to, because there is a huge amount of anxiety that is caused by losing short-term memory (you are constantly thrown into situations where you can’t make sense of what’s going on). So my mother-in-law for example, stopped cooking for herself long before some of the other symptoms really became apparent. She told everyone she was “bored of it”, and when cooking for a larger group she wolud constantly check and recheck the recipe. At the time it drove me crazy but then later when she was diagnosed with Alzheimer’s it all started to make sense.
