One of the biggest issues/emergencies facing oldies in their own home, especially if they live alone is falling and not being able to get up. That includes not reaching a landline phone or mobile on the kitchen bench, if granny still has a landline buy her a duress pendant to go with it.
Many die on the ground where they fall because they live alone and no-one finds them for days. Many more die from complications arising from falls within the next 30 days. Give them a landline, mobile phone and a duress pendant!
Finding someone passed away on the ground because they couldn't get to a phone or didn't like wearing a pendant is an utter waste. I've seen it first hand countless times.
They hate wearing the pendants and stuff but get them wearing them when you have half a chance of reasoning with them before they turn into stubborn old farts
