While in the shower, my nose started bleeding profusely. I have never had a nose bleed as severe as the one I had on this day. It became so bad that I thought I might have to go to the hospital if the bleeding continued. Fortunately, however, my nose stopped bleeding soon after I had this thought.
This nosebleed seemed to affect my health, as the amount of exercise I was able to do after the nosebleed dropped sharply, by about 30%.
