Excellent links giving information on anal fissures -- prevention, symptoms, etc. Brothers and sisters in poop, if you or anyone you know has an asshole in distress, take it to a doctor!

1) Lets talk about Hemorrhoids with Dr. OK. "This is a homepage for all the people who suffer from hemorrhoids. Please enjoy these pages without sitting too much infront of the computer ; we don't want you to develop hemorrhoids reading this!" A Japanese site, from the folks who obsess about and have invented the world's most sophisticated toilets. Maybe Dave can find a way to interview Dr. OK; though we will need an interpreter--the doc is not a native English speaker.

2) "Serious Study of Anal Diseases." Dr. OK is not kidding. In the section 'Observing surgery,' he thoughtfully warns you not to select the link 'if viewing blood makes you uneasy.'

3) ***The good doctor gives nifty eye catching graphic of a rectum in distress. If you own Photoshop, you can use this to create your very own Christmas card... or perhaps a Valentine, or perhaps a resignation letter to your company. If you click 'surgery' you'll get to see pictures of various kinds of asshole surgery. If you ever get bored with eating fiber every day, view the pictures, and you'll be inspired to stick to your high-bulk diet..
