17 gardening
18 Тут грань очень тонкая, но я так распределила:
Women: astrology, knitting, sewing, aerobics in the water
Men: model trains collecting, playing football (хотя вроде и женский есть футбол), parachuting, riding motorbikes, exploring volcanoes and underwater caves, fishing, diving
Both: playing chess, mountain climbing, reading, animal communication, horse riding, photography, yoga, cooking, travelling, dancing, computers, fashion, windsurfing, playing the piano, collecting postcards
