Zoegirl had posted about the value of cohousing being a benefit for those who chose to live together for companionship. I have been looking in the media to see if this option is seen as viable. CBC has this ["https://www.cbc.ca/news/health/seniors-cohousing-baby-boomers-loneliness-mental-health-1.4952142"] article about three longtime friends who sell their houses and find a shared living space that serves them well. It is interesting to read actual experiences.
I think it would take fairly congenial people to cohabit in this setting. I am not sure that I could do this. I wonder how many others would be able to do so?
