HELP!

Why do we do some things and don't do other things. I thought maybe you'd help. If you have some answers, my email is [email protected]. And I really would like to hear from you. So here we go. When you sneeze somebody will say God bless you, or gesundheit, or SOMETHING. But when you cough, nobody says a word. Why is that? And why do people put their cell phones in their hip pockets? Are they preparing to send pictures of their butts to favored groups of friends? And speaking of cell phones, why don't we encourage index finger twiddling? We're all guilty of twiddling our thumbs sometimes, and when we used our thumbs for writing with a pencil or a pen, that twiddling probably helped develop our thumb muscles, but it doesn't do any good any more, because we don't write anymore. We now type into our cell phones...using our index fingers. So why not index finger twiddle?
