Here’s one reason it’s a good idea to donate blood
They wouldn’t have known this had they not donated their blood in the first place.
That’s why you don’t just go and donate your blood – a blood donor must also answer questions about his medical history and take a short physical examination to make sure the donation isn’t hazardous to his health, says Wikipedia.
Obviously, the donated blood was disposed of immediately as using it in transfusions could have been disastrous, says SCMP.
But blood donation can actually bring health benefits – other than the obvious one of helping to save someone else’s life.
