The Japanese beat us

my first encounter in Japan:might start by sounding a bit gross but this is not the point :)
the toilet mechanism:
as u know in almost everywhere in the world they don't use our famous, worth nobel prize invention called el shatafa....guess what....the japanese beat us.when u sit on the toilet you have this dash board infront of u with buttons giving u the luxury of using the following options:
1- seat is already heated
2- you press a button for el shatafa to work
3- you can change the direction of el shatafa in
4 different levels 4- you can choose the intensity of water coming out
5- there's this button that says massage....but wouldn't dare to try it besara7a
Surprise: when u r done, you can choose to have hot air coming from inside as a dryer!!!!!!!!! no need for toilet rollof course to discover all this i had a couple of bad reactions like standing up to understand what exactly this button was doing and suddenly the water just burst into my face!!!!!that is the a must try kind of invention :)
