I find the statement that "investing is not an option" for the over 75's ill-informed, ageist, patronising, and offensive.
Being over 85 ourselves , investing is still the only option we consider. We've reached a stage where we need to pay for help with cleaning and gardening, but may one day need more expensive end-of-life care.
Securing, by investing, the best income stream from a sensible investment strategy is proving itself, so far, to be totally worthwhile.
