1 One out of every 10 people entering a hospital needs blood. 2  Just one pint of donated blood can help save as many as three people's lives. 3  The average adult has 10 pints of blood in his or her body.

A donor who regularly donates blood can lose a significant amount of weight, but it should not be thought of as a weight loss plan by any means.To donate blood the American Red Cross requires donors to weigh at least 110 pounds and maintain healthy iron levels in the body.hole blood donors can also donate platelets 72 hours after a whole blood donation, and vice versa. Blood donors must be 17 years old in most states, with some states lowering the limit to 16 years old with parental consent.
