把这一句，留给此刻的你
One bit of advice someone gave me - which I haven't yet tried - is that if you go to an area where you might pick up a tummy bug, you should seek out the local probiotic yogurt. Eating it will introduce you to the local gut flora, apparently.
有人给了我一个建议——我还没有尝试过——如果你去一个你可能会染上胃病的地方，你应该找当地的益生菌酸奶。显然，吃它会让你了解当地的肠道菌群。
