 Based on what we have heard today about the waterborne disease, the life cycle, how they circulate in the environment, and we have known that proper education, if this is your friend and your friend gives you something to eat, vegetables, you say, oh please, let me wash again, or wash it again. That is education. You are also letting your friend be aware of the fact that maybe it is not always, it may be because research has shown that even on salad research have shown that parasites were being found in it. So we don't trust, we have to, I mean, do what we apply, the knowledge we have. And in anything, when we come from, we don't know, some people that come from the toilet, we have the disinfectant there and everything, we have to disinfect our hands because we don't know whatever we touch, we don't know whatever we carry.
