In the chair of Economic Theory, there is talk at some point of "leisure" because there is much talk of "work." I did not intend frivolity when there are sensitive, close wars. It can be said that everything that is not work is leisure. This does not mean that one is indulging in pleasures. In wars, there is also free time, and the most paradoxical thing is that one can be on the front lines and be at peace. Talking about 1000 proposals for leisure and free time, I acknowledge that it was a hasty phrase and may offend.
