[quote name='Chika']the vegus nerve ends as a nerve bundle near your colon about 2-3" up from your rectum. some people's nerve ends right next to their colon. anything going through your anus (taking a massive dump, getting an emema, buttsechs, etc) has the possibility of stimulating that nerve. in most people it leads to slightly decreased heart rate which makes you feel calm and happy. not everyone gets stimulated by the same thing in the same way, but that's what causes you to feel great after droppin your kids off at the pool.[/QUOTE]
With an analysis like that I don't think I will ever be able to enjoy going #2 again.
