Young people, particularly, need the joy and force of life. Healthy sport, swimming, racing, walking, bodily exercises of every kind, and many-sided intellectual interests. Learning, studying, inquiry, as far as possible in common. That will give young people more than eternal theories and discussions about sexual problems and the so-called ‘living to the full’. Healthy bodies, healthy minds! Neither monk nor Don Juan, nor the intermediate attitude of the German philistines. You know, young comrade…?

— Vladimir Lenin, 1919
