In Britain it is illegal to use a phone while driving. You have to stop your vehicle and switch off the engine before you can legally use a cellphone. This is because surveys have shown that phone users are a significantly higher accident risk and there have been fatalities directly attributable to cellphone use.
Personally I want to enjoy life. I don't even check my email every day - every other day, maybe, or even less often when I'm on vacation. As for the cellphone, I keep it switched on most of the time but it's just a phone, and if it's switched off, my voicemail will handle any messages. What's the point of living if you're a slave to electronic gadgets?
