Hello.
There is a simple and enjoyable solution to all of this malarkey.
One of my very generous patients gave me, as a gift, a cell phone "jammer".
This interesting little toy is about as illegal as a radar detector (or so I am told).
It looks very much like a regular cell phone, thus, you will not be suspected of anything once you decide to take control of your surroundings.
Once activated, it disrupts and shuts down every cell phone for a 75 foot radius.
I use it in my clinic(people will talk on it while I am doing an examination on them!);while teaching at the university; in the movie house; restaurants; and, especially after landing after a plane flight, and the captain says "you may now use your electronic devices".
Of course, there is no cell phone usage "allowed" when I am in the gym

.
It depends on my irritation levels.
But, in any event, I enjoy silence everywhere I go.
Best,
Dr. D
