@Ahri 受凉感冒，可能是因为春夏交替的季节病毒更活跃，而这时候也正是容易“受凉”的时间。温度不稳定，没穿对衣服就会被说容易着凉。然而我觉得纯属胡说。。。

--摘录--
1.
Common Cold

Despite the popular belief that vitamin C can cure the common cold, scientific evidence doesn't support that theory. Taking vitamin C supplements regularly (not just at the beginning of a cold) produces only a small reduction in the duration of a cold (about 1 day). The only other piece of evidence supporting vitamin C for preventing colds comes from studies examining people exercising in extreme environments (athletes, such as skiers and marathon runners, and soldiers in the Arctic). In these studies, vitamin C did seem to reduce the risk of getting a cold.

2.
Precautions

Because of the potential for side effects and interactions with medications, you should take dietary supplements only under the supervision of a knowledgeable health care provider.

...

Vitamin C is generally considered safe because your body gets rid of what it does not use. But at high doses (more than 2,000 mg daily) it can cause diarrhea, gas, or stomach upset. If you experience these side effects, lower the dose of vitamin C.

@gzelvis 如果已经出现感冒症状，这时候吃维 c 一点用都没有。 维 c 不能长期大量服用。

@debiann 我忘了 Apple ID 和 iCloud 的 2FA 是分开设置还是同时设置的，刚才试着登陆这两个账号，没有验证码一个都进不去

@ahhui iCloud 也可以设置 2FA 。不用担心手机丢失会无法收到验证码，因为还有 recovery key 。
