Is It your habit to wash your hands after using toilet and before after eating?

Yes, of course. It's unhealthy not to, lol. Just think about how many bacteria you pick up just by using the toilet (wiping and flushing). Not to use soap and water afterwards is disgusting! As to mealtime. Think about how many things you touched that day. They all can have bad stuff on them. If you don't wash your hands before a meal, even with proper table manners (knife/fork etc) it still can't up in your food and in your mouth. And you never know how much food may end up on your fingers after a meal. Again, just proper to go and wash hands. And brush your teeth while you are at it;)
