Develop any other skill; turn to any other branch of knowledge; learn how to use your hands. Try woodworking, bird watching, gardening, mushrooming, cooking, fishing, sailing, weaving, pottery, zoology, astronomy, cosmology, take your pick. Whatever activity you engage in as trade or hobby, or field of study, will tone up your body and clear your head. At the very least, it will help you with your metaphors.
