I wondered aloud today whether I should worry about all the blood I ' m losing to karate bruises . Beth said it was probably good for my body because it forces me to produce clean , fresh blood . So I got some fresh bruises on my lower legs and upper arms today . Ironically , I ad pads on my lower legs , but still managed to bruise them soundly .

Question: Why is the writer getting bruises ?
Answer: Bruises are good for the body .They 're worrying too much about blood .None of the above choices .They 're getting hit with strikes in the karate class .
