My parents are in their early 60s, both retired. They sit at home all day miserable, watching TV, internet shopping for tat, scrolling Facebook, and sometimes do some gardening. Both are in good health, although my mum is a serious hyperchrondriac eg. she gets a mild tension headache and takes to her bed for three days (no exaggeration), worried she has a brain tumour. When me or my sister visit and offer to take them to lunch or something, they usually can't be bothered, are anxious to leave the house, or my mum didn't quite get 10 hours sleep so she's not feeling up to it. I think if they got out more they'd be happier but they're not interested. Aibu to just give up trying and accept this is the way they are? And stop putting any effort in? It just makes me sad that they're just sitting there wasting away mentally and physically.
Everyone else's parents around the same age are out living their lives. Playing sport, enjoying hobbies, travelling, and love having their kids and grandkids to visit. I think living like this will make them age 10x quicker. This kind of happened to one of my sets of grandparents, so you'd think they'd know better, and this really annoys me.
