I saw that many people donate blood every week at school, but today I heard that the blood center is ischemic and I need someone to donate blood to treat the disease. I don't understand,

I analyze three reasons: the blood we donated is still relatively small for the accident, so there will be insufficient blood supply.

Second, blood collection in hospitals is actually used to sell money, but it is a bit like insurance. When blood donors have problems, they can get blood for free. So the hospital has also made this a business, a stable business! After all, the possibility of an accident to a blood donor is very small.

Third, the attitude of coming in to collect blood is chilling, so I won't give many examples here. Last time I donated blood, damn it, I didn't eat a bottle of milk, and I was forced to donate 400CC, so it was my last blood donation. As for blood donation, I may get AIDS, and everyone is afraid.

To sum up, donating blood is not equal to donating blood. Brother Wang Tai, if you agree with me, please adopt it. Thank you very much.
