Unsure how I feel that of all the college undergrad courses I took, the two I cite the most have been Nutrition and Religion.
On the one fin it's unsurprising because a good entry-level class for either of those is basically "day 1: take everything that Everyone Knows and hurl into a dumpster" which is very me on multiple fronts. On the other fin I struggle to think of topics I want other people to discuss with me less.
...
No wait, on second thought those are probably related.
