... I have always wondered if I should be washing my hands everytime right after I do something or handle something. Or if I should keep washing in my routine of before eating, after bathroom and when dirty looking.
You really didn't specify why you are asking if you should wash your hands "everytime" right after I do something, and why
is really what determines if you wash or not.
As nummi pointed out, fear of germs causes many people to wash very frequently. In reality, a little dirt won't hurt you, even if it gets in your mouth. Other factors are: will you be soiling things that you touch? will you look too unclean for work if you don't wash? do your hands feel sticky?
I aim for as little washing as possible because it disrupts the defenses of the skin. That leaves me with washing only when I have a reason to wash, a reason like not wanting to get other things dirty if I touch them with soiled hands.
