Cell Phone on all day?

We only use our cell phones so mine is on 24/7. I forgot it at home over the weekend and was freaking out all weekend. I don't feel that there is any danger for keeping it on all day. I put it on the charger at night time and let it charge for about 8 hours but I don't turn it off to do that.

The purpose of a cell phone is to be reached at any time or place, so I don't see the point in turning it off. I never turn my cell off.

I don't think it's more dangerous than keeping it on in certain parts of the day, but that's the point of a mobile phone, to be reached at any hour. Personally, i don't turn off my phone, not even in the night. It goes automatically into sleep profile, though, so most of the times, i can't hear it because i'm asleep :D
