Yep. I do not own a mobile-phone. Never had a "smart"-phone. Finally cancelled my last GSM subscription ~2003 after having not used it for long. Reason: the RF gave me headaches & concentration problems. Yes, its the RF. At home, everything is wired. I try to limit wireless exposure as much as possible. I have a fancy landline with phone book, speed-dial and answering machine. And email. And a postal address. Never lost a customer or a friend over not being reachable 24/7. On the contrary. Most people react with surprise and then envy when they discover I have no mobile-phone. Highly recommended.
