today's activity: commemorate the security guard's birthday by donating blood

hello friends, today my friend who is off work was invited to take part in a joint blood donation to commemorate the security guard's birthday so those of us who are off work must participate in a joint blood donor activity every year, blood donation is a simple thing to do but can make a big difference in the lives of people in need. According to the Indonesian Red Cross, blood is very important for a person's survival because it acts as a supplier of oxygen and essential nutrients for various organs in the body. This is why health institutions need blood to treat patients back to health.
