Yesterday, I donated blood for the first time in my life. I have wanted to in the past, but was a bit intimidated at the prospect.
I am so happy I did. It wasn't painful at all, I didn't feel light headed or weak afterwards (I made sure to eat and hydrate beforehand), it didn't take as long as I thought it would; and my arm does not hurt at all and no signs of bruising (I did have a very cooperative vein, btw).
And, I have an excuse to take it easy for a couple of days. It isn't like I don't already take it easy when I want to, I just have a good excuse for it .
