"Nor can it be lack of exercise for I walk all day long"

I like the story of Kierkegaard going to his doctor as he says in a journal entry 1845. he had complained about being out of sorts.The doctors reply was "You have probable drunk too much coffee and you don't walk enough!" Three weeks later he was speaking once more to the doctor "I really do not feel well" Soren said " But it cannot be the coffee, for I do not drink coffee." "Nor can it be lack of exercise for I walk all day long". "So the reason must be that you don't drink coffee and you walk too much!" the doctor replied. Soren concluded his infirmity was on him because he drank coffee or if he didn't drink coffee his infirmity was because of that. He reckoned that this was a human affliction that all had to deal with.
