A month or so ago I took a funny turn at the Men's Shed & was ambulanced off to hospital for tests & observation. There's an emergency call button in the Shed that's supposed to notify emergency services. Except when, about 5 years ago, the venue (a retirement village) went fully digitally monitored interstate this circuit was left to do nothing except ring a single phone in an unmanned plant room. No-one knew the phone was ringing. Normally I'd have called on my iPhone but I was the victim in this case & somewhat out of it.
