Lots of people can't, Chris. Radio/telly/IPod on all day from the moment they get up. It used to annoy the hell out of me, now it just baffles me.
That's me at home. Radio on most of the time (radio 4) and if not, the telly, even if I'm also reading or knitting. It's company. I can put it to one side, mentally, if I need to, but I like to have some noise around. Otherwise, I'd get very lonely and introspective.
When I'm out, as a pedestrian or cycling, I don't need the noise for short trips, but I like to have the option for a longer ride or walk. As I've said, I'm confident that I don't have it loud enough to distract me, or stop me hearing traffic - I've consciously thought about it while I've been out, and checked how soon I hear stuff behind me. I guess the fact that I can zone the music out when I need to means I can snap to attention when necessary.
I wouldn't assume everyone can cope, but I can understand those, like me, who can do it.
