The question for me is, how do I convince them to do anything? I've tried sharing all the stats, buying them a peloton, using scare tactics. Everything. At a certain point you can't convince someone to do anything and unfortunately as one of their children I will have to take care of them like adult toddlers and watch them decline.
Just trying to convince my dad to not fall asleep on his couch watching tv is impossible. They are actually hopeless and I'm already starting to see signs of dementia.
