The bacon thing is maybe a good example of Hamming's Closed Door Paradox:
I noticed the following facts about people who work
with the door open or the door closed. I notice that
if you have the door to your office closed, you get
more work done today and tomorrow, and you are more
productive than most. But 10 years later somehow you
don't know quite know what problems are worth working
on; all the hard work you do is sort of tangential in
importance. He who works with the door open gets all
kinds of interruptions, but he also occasionally gets
clues as to what the world is and what might be
important. Now I cannot prove the cause and effect
sequence because you might say, ``The closed door is
symbolic of a closed mind.'' I don't know. But I can
say there is a pretty good correlation between those
who work with the doors open and those who ultimately
do important things, although people who work with
doors closed often work harder. Somehow they seem to
work on slightly the wrong thing - not much, but
enough that they miss fame.
In this case, as it turns out, bacon does give you cancer. The relative risk of high "processed meat" consumption is in the neighborhood of 20%, i.e. RR of 1.2, for colorectal and lung cancers. https://www.ncbi.nlm.nih.gov/pubmed/16991129/
In the US, there are about 200k deaths per year from these two cancers, out of 2.7 million total deaths. So your chances of dying of one of these two cancers is about 7.4%, if you live in a place somewhat like the US. And that increases to about 8.9% if you eat a lot of processed meat.
It seems to me like a 1.5% chance of dodging a death by cancer, and thus living an extra 5–20 years, is worth a single disrupted morning.
