Today I gave blood.
I try to give blood a few times a year. It is such an easy thing (for most people) to do, and one pint of blood can be used to help up to three people. And you never know when you, or someone you know, may be in a situation requiring blood from blood banks.
Also, it takes almost no time to donate. In about 30 to 45 minutes you are done. This is another reason I give blood, sometimes I am just too busy to volunteer in other ways, but I usually can always find the time to sit down for a bit with a needle in my arm. And you really can’t even feel it!
