@thecardsharp2 @luckytran At 10k/day, society would be shut down down to direct effects of death and disease. Remember January when schools were "staying open" despite sick teachers by packing students into auditoriums, and many businesses shut down due to sick workers. That was <3k/day.
@幸运的是，如果每天10公里，社会将因死亡和疾病的直接影响而关闭。还记得一月份吗？当时学校不顾生病的老师把学生塞进礼堂而“开门”，许多企业因工人生病而关闭。那是<；3公里/天。
