There is a great need for blood donations around the world, and you can be the means of saving lives. According to the American Red Cross, over 40,000 blood donations are needed every single day in the United States alone, and without the help of volunteers like you, it is impossible to fill this need. About 9.2 people donate every year in the US, and although approximately 38% of the population is eligible to donate, less than 10% of them actually do.
Sometimes people don't donate out of fear, but the process is relatively simple following a four-step process: registering, getting your medical history checked, donating, and having some refreshments (food and drink that you are given right after you donate to replenish your fluids and energy). And once you donate, you have the ability to donate red blood cells every 56 days.
So, carefully consider becoming a donor. You can save lives.
