Stomach ache-o-meter
At the age of 2,
stomach ache was caused by what was picked up from the floor and put into the mouth;
at the age of 10,
stomach ache was casused by the burger in the lunch box or flu bugs from the kids at school;
at the age of 30,
stomach ache can be caused by worry about the future, fight with friends, illness of loved ones, tomorrow's presentation, or the cold left-over chinese food from last night's delivery.
