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.
Possibly because you go out less, around a smaller set of people and/or aren’t doing as many gross / close things as younger people.
