2. I think we have kinda been focusing on "loners" more
as people along the whole spectrum of defining "loner".
In my working life, I used to give lectures to hundreds of people at a time, work with groups every day, spend hours in meetings and surrounded by staff.
In my non-working life, I preferred to be alone, every weekend when I could.
and in retirement, I fill the car up every 3 months...never go anywhere if I can help it.
We arranged our retirement so we can stay home all the time, which is where we are happiest, and find prolonged people contact uncomfortable.
Of course, on DU and the web, we all have a choice of how much interaction, when , we want. that suits me fine.
Where is your boat, if I may ask?
I think the idea of living on a boat has crossed a lot of people's mind at least once.
