> What's wrong with emergency calls going to voicemail, for your personal line when you aren't an onduty first-responder?

If I'm available I don't want to wait to find out a family member was in an accident or something.

> Would you also take your phone into the shower with you so you don't miss a potential call?

No, because I'm in the shower for less than 10 minutes. If some kind of emergency unfortunately happens while I'm in the shower then I guess I'll just have to find out after my shower. I can live with that.
