Yes, a very complex subject and an emotional one. Over the years I have seen a number of changes to 'care'. When I was a teenager, my grandmother had a stroke and was partially paralysed. She was cared for in hospital for the rest of her days (nine years).
An uncle had a stroke ten years ago, also partially paralysed as a result, and he went to a nursing home which he had to fund from his private pensions and state pension. My MIL paid a top fee of something like £65 per month.
My (late) MIL was very ill towards the end of her life. She refused to go into a nursing home leaving me and my DH to cope with her deteriorating health. We have an adult disabled son, who also needs care. Those years were difficult and exhausting. We never expect to inherit from anyone - if it means a house has to be sold in return for a care package, then so be it. I suppose you could look on it as a form of saving for the future, if you like.
So, us. Hmm, I wonder what's in store for us. Our house will need to be a form of financial security for our son, who will never be completely independent. What we are doing is 'age proofing' our house now - making changes like turning the bathroom into a shower room, adjusting step heights at the entrance to our house etc. We have 'rainy day' savings to help fund any professional care we may need or to fund further adjustments to our home. This might seem rather pessimistic, but having witnessed the current form of care, it scares me. I'm in my 50's and 'old age' seems a long way off yet, but we believe in planning for the future while we are still in the best of health and able to do so. We may have to make adjustments on the way, but we are open minded.
