Mr. Healthy

the park after work. He gets up very early in the morning and goes to work on foot. He is a
vegetarian and always buys his fruit and vegetables on a farm near our town. He always
drinks fruit juice and water. He goes to bed at 10 p.m. he hasn’t got a TV set at home but he
sometimes buys the newspaper and listens to the music.
