How do blind people know when to stop wiping

Do you have to look at your bum every time you need to wipe it to stop? No didn't think so.

Really, do you need to look at your bum every time to know when to stop? Think about it. Thanks for using ChaCha.

Blind people have a keen sense of smell, so perhaps they smell of the paper. Or, perhaps they feel with their hand. ChaCha!

Possibly blind people just have a sense when enough is enough. They do it everyday just like humans with sight after all. ChaCha
