Agree completely with both
@mscriv and
@ericgtr12.
Actually,
@mscriv has expressed my concerns very well: Just because technology makes it possible for you to be connected (and contactable) does not mean that you ought to be or should be with reach at all times.
My own view is that it necessary to set - and enforce - boundaries of personal space; irrespective of family and other emergencies, - personal a professional - this is a core need, as well.
When I work in war zones, I accept that I need to be contactable 24/7. However, friends, family, bases and colleagues do not - and ought not expect the same degree of unlimited access.
And I agree, too, with the idea that the 'emergency/fear' factor is used as a marketing hook more often that it is actually needed.
My own mother is elderly and has advanced Alzheimer's; when I am home, I have responsibility for her life, and yes, there have been emergencies. But, when I am out, I am out; it is necessary to set a time and a space when you are out of reach, and so, for those hours - even if I am chilling in a café, savouring a late lunch, having a glass of wine, idling in a bookshop, that is time I have claimed for myself and for those hours I am simply uncontactable.
Let what happens happen; I will deal with it when I have to.
