I think that's extremely dangerous and I would never consider this to be honest. My phone is my only phone, and I need to be able to call emergency services, or answer an important call, at unexpected times.
If I reached the point where I was comfortable literally being unable to use my phone for a period of time, I would just not have a phone or not carry it with me.
