1. Some big questions are not asked:
    – what sort of responses to an emergency are provided?
    – do you need any automatic monitoring, like flood alarm, blood pressure, falls monitor?
    – have you considered what service your local authority provides?
    – can you get your local authority or health service to pay for it?
    – can it be used to contact friends and family?
    – can it provide video conversations?
    But you could write a book about it.
