We've been getting the lifestyle check offers ever since we moved here 7 years ago.
I think the over 75 health check is a really good idea. If not for my peace of mind, then for my family's. I know several people at the moment who are going through hell because of fibbing older relatives, telling their doctors that they are fine when they are not, and so not getting help when they need it. My cousin's father has just been refused an evening carer because he said he was making a sandwich before she got there, so didn't need her. He wasn't, and now he has no-one to check on him in the evenings and no help unless his children take it in turns to drive an hour away. I think a doctor would be able to tell if he was malnourished, at the very least.
