Blood Donation: A Gift of Life
Every two seconds, someone in the world needs blood. From accident victims and surgery patients to mothers in childbirth and children with leukemia, millions of lives depend on the generosity of blood donors. Yet less than 1% of eligible people actually donate. Blood cannot be manufactured in a lab; it can only come from caring human donors. A single donation - taking less than an hour - can save up to three lives.
