由于幼年时家境贫寒,长期营养不良,才四十不惑的我却患有慢性胃炎、类风湿关节炎等多种慢性疾病。虽然并不是很严重的疾病,但老毛病发作时,也严重影响了我正常的工作、生活。我也曾采取过跑步、打球、跳绳等体育锻炼,但健身效果却并不明显。 I am suffering from chronic gastritis, rheumatoid arthritis and many other chronic diseases when I am still young and have poor nutrition and long-term malnutrition. Although it is not a very serious disease, the old problems have also seriously affected my normal work and life. I have also taken physical exercise like running, playing ball, jumping rope, etc., but the fitness effect is not obvious.
