"I have never taken any exercise except sleeping and resting"

Mark Twain's quote is a funny method of expressing his absence of physical activity. He is suggesting that he does not take part in any exercise other than sleeping and resting. This could be translated as a joke, as it is not likely that someone would not participate in any physical activity at all. It could likewise be translated as a commentary on the value of rest and relaxation, as Twain is suggesting that sleeping and resting are simply as essential as physical activity. It might likewise be analyzed as a criticism of the contemporary way of life, which typically highlights physical activity over rest and relaxation. Whatever the analysis, Twain's quote is an amusing way of expressing his lack of physical activity.
