Life in a retirement residence certainly can be very taxing for those who still have good cognitive abilities - this was certainly the experience of a few people from my church who moved in recent years - often because of the decline of a spouse. It is a positive environment in so many ways, but for some I think the lack of option to set one's own schedule is huge - eg to eat when you're hungry, not when your 'shift' is in the dining room, to eat with others, to choose with whom to sit at mealtimes etc. - these are things I heard others speak of, some of which I hadn't ever considered. Also, sometimes the recreational activities may be designed for those with altered physical & cognitive abilities - thus feeling less than interesting for others.
So I'm glad you've still got the farm to visit - family to chat with, real life 'problems' - mechanical or otherwise! - to solve, projects & places to tinker and feel engaged, fresh country air to breathe and night sky to wonder at, food and sleep of your choosing. Enjoy the rest of your week & safe travels back to the city Naman.
