Nowadays there is a commonly held belief that donating blood will do harm to a person’s health. Actually, it is not the real case.
On the one hand, the small amount of blood donated will be recovered in a short time.
On the other hand, with the development of medical science, it is much safer and more convenient now for people to donate blood.
Most important of all, donating blood canhelp save the lives of dying patients, which is significant to the whole society.
We need to carry out several measures to promote blood donation.
First, we should impart medical knowledge to common citizens, convincing them that blood donation is not dangerous at all.
Second, we should help people realize tha thelping others is equal to helping ourselves, not only because it is a virtue to be ready to help others, but also because one day we will be those in need of help.
