Re: I'd go further than that personally
You should be careful about such blanket statements. I had chemo last year an it damaged my hearing. I'm not deaf but range is limited and I can't always tell what sounds are. I have a pebble steel. It lasts for about four or five days between charges and I don't miss calls from the Mrs. or my GP (or telemarketers unfortunately) anymore because it's hard to miss the buzzing thing at the end of my arm which is much more discrete than a small disco going off in my trousers or on my desk.
