How to give blood
It made me 
"It doesn't take long. It isn't painful. Everyone is pleasant and you are helping someone else."
How I did it: I went to my local blood bank and signed up. They did the original screening and now every few months I go back to donate blood.
I also signed up to be a tissue and marrow donor if there's a match.
Lessons & tips:
- Eat before you donate.
- Drink plenty of water.
- Relax, they are professionals.
- Allow yourself time to heal after donating.
