I am a male, just turned 62, and noticed twice recently some blood passed through my uretha. I found it in my shorts. I have never seen it in my urine. The last time (this week) it appeared to be a significant amount (tablespoon?). I am healthy, weigh 165 lbs, eat most fresh fruits and vegetables and exercise almost every day (running/walking, 3-6 miles, small amount of weight lifting, push-ups and sit-ups). No other pain or discomfort. I plan to go to a local doctor about this but was curios about your take on this matter. What could cause something like this? The blood appears to be fresh (bright red as opposed to brownish).
