People have different views.
The op has been very live and let live, you do you and I'll do me. But others can't seem to get it... that what they like ie homes and gardens aren't what everyone likes.
Family visits and care from others. Cruises and hotels. Travel or staying local. Care homes or staying home and possible dying so you never have to go into a care home. A combination of all of this to suit.
We all make different decisions in life at all ages.
Many seem to have misunderstood that the op would be spending £1m or more by age 75 and then if still alive, ie changed her mind, she still has £30k pa pension, which is more than the average person has in pension pa and that is before state pension.
She will not be living in poverty.
Not a bad position to be in at over 75 and if the op is still willing to be alive.
On a side note, if people want to die, they should be allowed. You don't need state allowed euthanasia. Suicide has always been an option, people can be very ingenious when they actually are ready and willing to take their own lives.
Yes they may have less choices due to being ill and infirm or maybe not, a lot of people on here are mentioning active and quite well people in their 80s.
As before live and let live and die and let die.
How someone chooses to live and die, if not harming anyone is no one elses business.
