I have had a mobile phone for over 20 years and just do not use it a lot.
Since lockdown it is by my side all day but to be frank I just ignore it. My wife keeps complaining that i have missed texts. I used to use it a bit more BEFORE lockdown, but kust to look at the BBC website.
I do NOT use twitter. Facebook gets opened a couple of times a year. Whatsapp i use to call our sons and I also have a group that I keep in contact with. (But more of the time I just forget to look)
I do not use maps because i have satnav in the car, and to be frank i only use the car satnave a few times a year.
