I have yet to install Facebook or Whatsapp or similar. I think it would be the death of me. I spend way too much time on my phone/computer.
I was in a care giving role and felt it couldn't leave my side. Since losing that person, I now rejoice in being able to leave my phone. Heck I didn't turn it on yesterday. And it has been sitting in the kitchen all day today.
The telephone does fill me with existential dread as most communication with me is asking me for something or alerting me to something negative. Perhaps that's an age thing. Whereas the Internet is still pleasurable but a complete and utter time suck.
