Alright, guys. First off, it is not 'my logic', it is fact about pay phones and landlines. You make it sound like you're on call 24x7, in which case, I pity you. If you cannot afford some time off to just ride your bike without the distractions of everyday life, what a shame. I am not attacking you, I'm merely asking why life has to move so fast in general that you have to be that available? Are you the CEO of a Fortune 500 company?

Before you know it, we'll all accept that we have to be available 24x7 for whatever reason, then it's no longer life, it's work. I am on call every weekend. On my weekend rides, I turn the ringer up really high so there's no mistaking if someone calls. I stop, check the phone if I must, and do whatever is necessary. Nothing is so crucial that I have to have a headset in during my leisure time to immediately respond to a call. YMMV.

EDIT: Admittedly, life moves exponentially faster in this day and age. Availability and proliferation of information creates demands on our time that did not exist 35 years ago. I choose not to move as fast as the information curve.
