The thing with change is that usaly commes with new generations. Usualy the eldery who have build their habits, are not prown to change. This off course is not allways the case but it is dominant behavior. Staying open to new ideas and changes is getting harder with age, as the habits are bulid and permanent connection in the brain are established.
Yes, that can be, as the old saying was made to reflect that: "you can't teach an old dog new tricks" ;)
I find this quite disturbing acctualy, thinking how will I be in my old age :)
