But you then have to be in a "state approved" care home not the one one might choose to be in.
That depends on how long you intend to live... Care is not cheap, say £1000/week, 200k, 4 years...
An "old dear" probably has no other income than the state pension. It's only in fairly recent times that everyone has be told that making their own pension arrangements would be a very "Good Idea". In fact anybody who isn't making as much provision as they can afford to some form of pension arrangement is going to find their later life very tough. This applies even more so to the "youngsters", ie those below 30ish. Retirement when you are twenty something may seem a very long way off but £10 salted away and allowed to grow for 50 years of "working life" will be worth a lot more than £10 invested in the last
10 years...
