Wow! I am surprised about the blood donation, its a good thing, your a good samaritan in your own little way. Your helping other people by giving what you have from your body.
I never tried to donate blood, but i tried it once in fuchu, but that time they didn't allow me, because my blood is so low, because im not sleeping well that time. Oneday i will donate for the benefit of the other.
My bruise is ok, no problem. I kinda like it, having scars in wounds makes me stronger. It challenges my body even more. The adrenaline is rushing into my veins.
