In my opinion,there is no talking about serious if someone is irresponsible for one's life,modiocre is the biggest unseriousness. 在我看来，对自己的生命不负责任，就无严肃可言，平庸就是最大的不严肃。
With regard to varicella vaccine, the reluctance to vaccination were due mostly to the avoidance of medical interventions and perceived unseriousness of varicella. 69.;7%25的民众表示愿意接种水痘疫苗，不愿接种的理由多为尽可能避免医疗行为，以及自觉水痘并非严重的疾病。
