I feel like this post treats vigilance and paranoia as free. To act generally differently in my life to be a lot more paranoid and a lot more careful about things like getting background checks on people who work on buildings that I work in, I'd want to be convinced that this is actually a good use of time, and that a lot of people in my reference class should actually be doing this. I want to compare the micromorts to the amount of time it will take me plus some sort of fuzzy measure of social capital lost, the cost of being anxious, etc. I don't personally know of anyone who has died whose life would have been saved by any of the things you recommend — it might still be worth it, certainly some people do die whose lives could have been saved by the things you recommend, but the numbers matter. 

Some advice to avoid dying is actually really good. But a lot of people make their lives a lot worse with paranoia, hypochondria / health anxiety, and caution about the wrong things. I didn't like this post because I don't think it provided good evidence to its readers that it was accurately discerning between what's worth doing and what isn't worth doing (even if it was in fact doing so)

I have the same problem. Often, if I have food scraps I expect will smell bad, I put it into a gallon-sized ziplock bag, then close that, then put that in the trash, which I find helps (and is less gross to me than taking the whole bag of trash outside then having to replace the bin liner more frequently). 

I think some of these are really neat and interesting ideas. I will keep them in mind, but also encourage you to think about whether you might actually be the best fit for this project (as far as I know no one has done it so far but you, it's hard for people to absorb one anothers' models and enthusiasms, I doubt we will get a ton of applicants).
