While the health related issues due to constant use of mobile phones have not been proven (atleast to the scientific community), somehow I am uncomfortable using my mobile for many months now. Often I get pain in the ears + a burning sensation. Nowadays I try to use more of landline, which doesn't cause this type of trouble. I don't know if it is a problem due to my instrument (alone) or it is a general problem faced by many users. Somehow the old charm of using a mobile is gone. I find e-mails coming at late nights - thus even sleep is disturbed. Sometimes, if I happen to read them then the sleep for the night is gone... as I start thinking about how to attend to the mail the next morning. I think it was much better 10 years back when office work ended within office itself.
