I once read a really interesting article, can´t remember where or when, which said that most of us, who were born in the 1950s, were brought up on the method of putting very young children on the potty before they were ready. The consequence being that we now are not able to hold our wee in, flexing the wrong muscles, or something to that effect. It is certainly the case for me, when I need to go, I need to go. Whenever I travel anywhere, I have the public toilets mapped out. The answer is not to drink anything for a while before leaving home, which definitely is not healthy. I remember my mother stopping me from drinking before going anywhere. You couldn´t do it with today´s young, who are forever sipping from water bottles. Probably better for them in the long run.
