As a child, Pavlov willingly participated in house duties such as doing the dishes and taking care of his siblings. He loved to garden, ride his bicycle, row, swim, and play gorodki; he devoted his summer vacations to these activities.[11] Although able to read by the age of seven, Pavlov was seriously injured when he fell from a high wall onto a stone pavement. As a result of the injuries he sustained[12] he did not begin formal schooling until he was 11 years old.[9]
