@Non it's part of aging actually. they cannot control their health anymore even with the most effective medicines out there. because as you age, you lose nerve fibers and the nerve cells communicate slower than before when you were young, and sometimes in the worst cases they cause dementia. which you can see, some of them are childish and aggressive. so it is the proggression. don't be mean to them, it is the part where they can't control, and i promise you they feel much worse than you. i will tell you one thing, older people are the nicest to deal in the hospital than the younger ones. becauase istg they are the sweetest and kindliest patients lol
