I have zero interest in social activities as well… That is my instinct as well… Yet I wonder if that’s a good plan. Due to my wife’s incurable illness I anticipate being widowed by the time I’m in my 70s. She’s been my best friend since age 20 (sniff). Social isolation is a really good predictor of how badly one will do as a senior, how happy / unhappy you will be when you finally depart. I hope I find the bravery to be more social when I end up alone.
