When I was a young boy I would get sick pretty regularly (headaches, fever, nausea, the works). Now that I’m a grown man I rarely experience such extremes. Instead I find myself in more of a long term state of vague apathy and shittiness.
That makes me wonder if my immune system truly has improved, or if I simply lost touch with my feelings.
One of my kids gets a lot of fevers and headaches. He also is a very picky eater, and doesn’t drink enough water. (We’re working on both of those.)
My other kid is not so picky, and rarely has fevers or headaches.
You can probably tell I have an opinion on the nature of these correlations.
