Archie, probably something to get checked out at some point. Could be related to the drinking but who knows. There's a chance they have you poop in a cup and then guaic it. If the guaic comes back positive, indicating blood, then you're likely gonna be set up for a colonoscopy. It could also be hemmerhoids (sp.), usually small amount of bright red blood on the toilet paper. Archie, are you wiping vigorously? Calm swipes, archie. Take it easy on NSAIDS as well.
The correlation between stress and cardiovascular disease is well documented. However I'm not sure of any well done studies that acutally prove a shorter life span. But I'm not a research nut. I actually hate it and am glad someone else does it. So I read studies as little as possible. But it makes sense. I wish Daft well.
