Donating Blood

I signed up today because we were having a blood drive at my office and I figured it was too easy to not do it. Of course a fellow employee reminded me the Stanford blood bank is just down the road, but anyways. For years I'd wanted to donate blood again but couldn't because I'd had too many tattoos or I was pregnant. I've been thinkign about why did I feel compelled to donate today? I can't come up with one happy answer, they ar all pretty grave. I have kids, and if something god forbid happened, I want to know blood is available. I drive a very long distance to work daily, I pass many accidents, god forbid something were to happen, I want to know there is blood available.
I'm not down about it or anyting, but rather answering questions in my head. I feel good that I did it, really good. I hope my A+ juice makes a difference to someone in need. I'm also glad to learn I am no longer anemic!
