Efftect on donating blood

Answer 1

Not only does donating blood save lives, it can also greatly improve yours - if you're a male. Women filter their blood monthly from having their period, whereas guys do not. When the body loses blood (naturally or through donation) the body makes more blood. This allows for 'dirty blood' that can have too much iron in it, to be 'watered down' and healthier. Iron rich blood can be hard on your organs, so it's a good habit to get involved with.
