If you have to go to the bathroom when your out.Why when you get closer to your house it gets worse
because the closer you get to the house the more of an anticipation you get to relieving your self. Because you know you will get to relieve yourself.
Your body recognizes the fact you do in fact have a bathroom in your house an urges your body to go
because you keep thinking about it
Since you have the sense that you have to go so bad and you know that your right by a toilet your in a need to rush and it gets worsen I guess
You realize that you are almost to the toilet and so your body is "excited" to get there and your bladder starts to push out the waste.
idk but this same thing happens when we know we'll have a kfc treat and when its on our table, mouth gets more watery
Probably because more time has passed and the urge is greater.
