After retiring, my uncle – a lover of the sea- took up a strange leisure activity : he spends most mornings at the beach, looking for things that the sea sends ashore. He says: It’s a multi-beneficial leisure activity. I can get some exercise, blending, picking up, and walking. I can breathe the fresh air and enjoy the vastness and quietness of the sea. Sometimes I watch the children playing beach games and I feel years younger. At the same time, I can also clean the beach. It’s volunteer work, isn’t it? Many of the things I pick up from the beach are still useful to someone. I clean them and sell them at the Sunday flea market in the town nearby. Do you know of any leisure activity that pays? Mine does! 1. When did the writer’s take up this strange activity? 2. Which part of the day does he go to the beach? 3. How does he feel watching the children playing beach games? 4.
